SL74HC623
Octal 3-State Noninverting Bus Transceiver
High-Performance Silicon-Gate CMOS
The SL74HC623 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 SL74HC623 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
