SL74HC620
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
