Datasheet Summary
TECHNICAL DATA
Octal 3-State Noninverting Bus Transceiver
High-Performance Silicon-Gate CMOS
The IN74HC623A is identical in pinout to the LS/ALS623. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The IN74HC623A is a 3-state noninverting transceiver that is used for 2-way munication 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
