Octal 3-State Inverting Bus Transceiver
High-Performance Silicon-Gate CMOS

The SL74HC620 is identical in pinout to the LS/ALS620. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
The SL74HC620 is a 3 -state 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
