TECHNICAL DATA
Octal 3-State Noninverting Bus Transceiver
High-Speed Silicon-Gate
CMOS
The IN74AC623 is identical in pinout to the LS/ALS623, HC/HCT623. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. The IN74AC623 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; 0.1 µA @ 25°C High Noise Immunity Characteristic of
CMOS Devices Outputs Source/Sink 24 mA
