IN74AC620
The IN74AC620 is identical in pinout to the LS/ALS620,
HC/HCT620. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS
outputs.
The IN74AC620 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; 0.1 µA @ 25°C
• High Noise Immunity Characteristic of CMOS Devices
• Outputs Source/Sink 24 mA
