SL74HC623 Datasheet (System Logic Semiconductor) - Octal 3-State Noninverting Bus Transceiver

SL74HC623, Octal 3-State Noninverting Bus Transceiver

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.
