TECHNICAL DATA
IN74HC623A
Octal 3-State Noninverting Bus Transceiver
High-Performance Silicon-Gate CMOS
The IN74HC623A is identical in pinout to the LS/ALS623. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The IN74HC623A is a 3-state noninverting transceiver that is used for 2-way communication between data buses. Two separate enables are available. The enable for bus A to B is active-high, the enable for bus B to A is active-low. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.
