High-Performance Silicon-Gate CMOS
KK74HC620A
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: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
