TECHNICAL DATA
KK74HC620A
Octal 3-State Inverting Bus Transceiver
High-Performance Silicon-Gate CMOS
The KK74HC620A 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 KK74HC620A 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.
