TECHNICAL DATA
Octal 3-State Noninverting
Bus Transceiver
High-Performance Silicon-Gate CMOS
IN74HC623A
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: 1.0 µA
High Noise Immunity Characteristic of CMOS Devices
