Overview
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.
