The MC144110 contains six static D/A converters; the MC144111 contains four converters. Due to a unique feature of these DACs, the user is permitted easy scaling of the analog outputs of a system. Over a 5 to 15 V supply range, these DACs may be directly interfaced to CMOS MPUs operating at 5 V. * * * * * * * * Direct R-2R Network Outputs Buffered Emitter-Follower Outputs Serial Data Input Digital Data Output Facilitates Cascading Direct Interface to CMOS P Wide Operating Voltage Range: 4.5 to 15 V Wide Operating Temperature Range: 0 to 85C Software Information is Contained in Document M68HC11RM/AD Package Information P Suffix Plastic DIP Case 646 Package Information DW Suffix SOG Package Case 751G Ordering Information Device MC144110P MC144110DW MC144111P MC144111DW Package Plastic DIP SOG Plastic DIP SOG Contents 1 2 3 4 5 Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Electrical Specifications . . . . . . . . . . . . . . . . 4 Switching Characteristics . . . . . . . . . . . . . . . 5 Pin Descriptions . . . . . . . . . . . . . . . . . . . . . . . 8 Packaging . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 Freescale reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.

For proper operation it is recommended that Vin and Vout be constrained to the range VSS (Vin or Vout) VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Table 2.

Six words are loaded into the MC144110 during each D/A cycle; four words are loaded into the MC144111. The last 6-bit word shifted in determines the output level of pins Q1 Out and R1 Out. The next-to-last 6-bit word affects pins Q2 Out and R2 Out, etc. ENB Negative Logic Enable The ENB pin must be low (active) during the serial load. On the low-to-high transition of ENB, data contained in the shift register is loaded into the latch. CLK Shift Register Clock Data is shifted into the register on the high-to-low transition of CLK. CLK is fed into the D-input of a transparent latch, which is used for inhibiting the clocking of the shift register when ENB is high. The number of clock cycles required for the MC144110 is usually 36. The MC144111 usually uses 24 cycles. See Table 4 for additional information. 4.2 OUTPUTS Dout Data Output The digital data output is primarily used for cascading the DACs and may be fed into Din of the next stage. R1 Out through Rn Out Resistor Network Outputs These are the R-2R resistor network outputs. These outputs may be fed to high-impedance input FET op amps to bypass the on-chip bipolar transistors. The R value of the resistor network ranges from 7 to 15 k. MC144110 Technical Data, Rev. 2 8 Freescale Semiconductor Pin Descriptions Q1 Out through Qn Out NPN Transistor Outputs Buffered DAC outputs utilize an emitter-follower configuration for current-gain, thereby allowing interface to low-impedance circuits. 4.3 SUPPLY PINS VSS Negative Supply Voltage This pin is usually ground. VDD Positive Supply Voltage The voltage applied to this pin is used to scale the analog output swing from 4.5 to 15 V p-p.
