DESCRIPTION
The 74GTL1655 devices are 16-bit high-drive (100mA), low-output-impedance universal bus transceivers designed for backplane applications.

■ HIGH SPEED GTL/GTL+ UNIVERSAL TRANSCEIVER : tPD = 4.6 ns (MAX.) A to B at VCC = 3V
■ COMBINES D-TYPE LATCHES AND D-TYPE FLIP-FLOPS FOR OPERATION IN TRANSPARENT, LATCHED, OR CLOCKED MODE
■ OPERATING VOLTAGE RANGE: VCC(OPR) = 3.0V to 3.6V
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL=24mA (MIN) at VCC = 3V (A PORT)
■ OUTPUT IMPEDANCE: IOL = 100mA (MIN) at VCC = 3V (B PORT)
■ HIGH-IMPEDANCE STATE DURING POWER UP AND POWER DOWN up to Vcc=1.5V PERMITT LIVE INSERTION
■ B-PORT PRECHARGED BY BIASVcc REDUCE NOISE ON THE LINE DURING LIVE INSERTION ■ EDGE RATE-CONTROL INPUT CONFIGURES THE B-PORT OUTPUT RISE AND FALL TIMES
■ BUS HOLD ON DATA INPUTS ELIMINATES THE NEED FOR EXTERNAL PULL-UP/ PULL-DOWN RESISTORS (A PORT)
■ DISTRIBUTED VCC AND GND PIN CONFIGURATION MINIMIZES HIGH-SPEED SWITCHING NOISE IN PARALLEL COMUNICATIONS .
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 1655
