| FIN1027 * FIN1027A 3.3V LVDS 2-Bit High Speed Differential Driver April 2001 Revised June 2003 FIN1027 * FIN1027A 3.3V LVDS 2-Bit High Speed Differential Driver General Description This dual driver is designed for high speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. The driver translates LVTTL signal levels to LVDS levels with a typical differential output swing of 350 mV which provides low EMI at ultra low power dissipation even at high frequencies. This device is ideal for high speed transfer of clock or data. The FIN1027 or FIN1027A can be paired with its companion receiver, the FIN1028, or with any other LVDS receiver. Features s Greater than 600Mbs data rate s 3.3V power supply operation s 0.5ns maximum differential pulse skew s 1.5ns maximum propagation delay s Low power dissipation s Power-Off protection s Meets or exceeds the TIA/EIA-644 LVDS standard s Flow-through pinout simplifies PCB layout s 8-Lead SOIC, US8, and 8-terminal MLP packages save space Ordering Code: Order Number FIN1027M FIN1027MX FIN1027K8X FIN1027MPX (Preliminary) FIN1027AM FIN1027AMX Package Number M08A M08A MAB08A MLP08C M08A M08A Package Description 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TUBE] 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TAPE and REEL] 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide [TAPE and REEL] 8-Terminal Molded Leadless Package (MLP) Dual, JEDEC MO-229, 2mm Square [TAPE and REEL] 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TUBE] 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow [TAPE and REEL] (c) 2003 Fairchild Semiconductor Corporation DS500501 www.fairchildsemi.com FIN1027 * FIN1027A Connection Diagrams Pin Assignments for SOIC FIN1027 Pin Assignments for US8 for FIN1027 (Top View) Pin Assignments for SOIC FIN1027A (Top View) Terminal Assignments for MLP FIN1027 (Top Through View) (Top View) Pin Descriptions Pin Name DIN1, DIN2 DOUT1+, DOUT2+ DOUT1-, DOUT2- VCC GND Description LVTTL Data Inputs Non-inverting Driver Outputs Inverting Driver Outputs Power Supply Ground Function Table Input DIN L H OPEN H = HIGH Logic Level L = LOW Logic Level X = Don't Care Outputs DOUT+ L H L DOUT- H L H www.fairchildsemi.com 2 FIN1027 * FIN1027A Absolute Maximum Ratings(Note 1) Supply Voltage (VCC) DC Input Voltage (DIN) DC Output Voltage (DOUT ) Driver Short Circuit Current (IOSD) Storage Temperature Range (TSTG) Max Junction Temperature (TJ) Lead Temperature (TL) (Soldering, 10 seconds) ESD (Human Body Model) ESD (Machine Model) 260C -0.5V to +4.6V -0.5V to +6.0V -0.5V to +4.7V Continuous Recommended Operating Conditions Supply Voltage (VCC) Input Voltage (VIN) Operating Temperature (TA) 3.0V to 3.6V 0 to VCC -40C to +85C -65C to +150C 150C 6500V 400V Note 1: The "Absolute Maximum Ratings": are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature and output/input loading variables. Fairchild does not recommend operation of circuits outside databook specification.
