BIPOLAR ANALOG INTEGRATED CIRCUIT
PC7073
PC7073 ANALOG SUBSCRIBER LINE LSI (BS-SLIC)
The PC7073 is a BS-SLIC that can be used in analog subscriber circuits such as private branch exchangers (PBXs) and switching equipment for central offices. It features two of the functions required for analog subscriber circuits: subscriber line feed control and subscriber line supervision. Use of the PC7073 in combination with a digital CODEC (PD9903) can reduce the number of components required in analog subscriber circuits.
FEATURES
* Single-chip, monolithic LSI (bipolar) * Constant-resistance feed or semi constant-current feed Note * 200- feed, 400- feed, or Tip-to-Ring pin feedout status (HIGH and WET) * On-chip metering signal superposing circuit * On-hook sending and receiving * Loop detection Note * Ground detection and ground-fault/power contact protection Note * Three on-chip relay drivers (flyback prevention diode must be externally provided) * Two power supply voltages (-48 V and +5 V) * Low power consumption: 110 mW (TYP., when on hook) Note Requires PD9903.

2. USE CAUTIONS
(1) Combined characteristics of PC7073 and PD9903 * The PC7073 is designed to be used in combination with the PD9903. Therefore, first half of the electrical characteristics described below are ratings for the PC7073 as a discrete unit while the second half are combined ratings that include the PD9903. * Subscriber circuit constants that are determined by factors such as termination impedance are configured to enable setting by external order parameters. Consequently, input of an order that is not suitable for the target impedance may result in failure to obtain the required characteristics. (2) Absolute maximum ratings Application of voltage or current in excess of the absolute maximum ratings may result in damage. Be especially cautious about surges, etc. (3) Load of by-pass capacitor Because the PC7073 and PD9903 use several internal high-frequency operational amplifiers, high power supply impedance can cause instability (such as oscillation) in these internal operational amplifiers. To suppress such instability and eliminate power supply noise, connect by-pass capacitors (CACOM = approx. 0.1 F) having superior high frequency characteristics as close as possible to the PC7073's power supply pins (VBB and VCC) and the PD9903's power supply pins (AVDD and DVDD). (4) Addition of ACOM pin connection capacitor The voltage of the ACOM pin between the PC7073 and PD9903 is the signal source reference voltage for the PC7073. Superposition of noise on this pin may have adverse effects on transmission characteristics. Therefore, make the wires between the ACOM pin and the two LSIs as short as possible, and connect capacitors (CACOM = approx. 0.1 F) having superior high frequency characteristics as close as possible to the pins. (5) Overcurrent prevention measures Due to its structure, power to the PC7073 must first be supplied to a low-voltage potential (VBB). Accordingly, if power is supplied first to a power supply pin other than VBB, an overcurrent will flow within the PC7073 (an overcurrent will not flow if power is input to all power supply pins). Therefore, if feeding to a power supply pin other than VBB first, connect an external diode and limiting resistor (rated at several ) in the directions described below. * Reverse-bias direction between VBB pin and VCC pin. * Reverse-bias direction between VBB pin and GND. * Reverse-bias direction between VCC pin and GND.

Notes on Handling Devices against Electrostatic Discharge
Caution When handling this device, special care against electrostatic discharge (ESD) must be taken. If a strong ESD is applied to this device, the junction parts of the internal transistors may be destroyed. Therefore, when transporting or storing this device, be sure to use the conductive tray or magazine case in the packing provided by NEC, or use a conductive buffer material or metal case. Also be sure to ground the operator's body and any tools that may enter in contact with the device during assembly processes. Never put or leave the device on a plastic board or table, and do not touch the device pins directly by hand.

No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in this document. NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
