KK74ACT620

Octal 3-State Inverting

Bus Transceiver

High-Speed Silicon-Gate CMOS

ORDERING INFORMATION

KK74ACT620N Plastic

KK74ACT620DW SOIC

The KK74ACT620 is identical in pinout to the LS/ALS620,

HC/HCT620. The KK74ACT620 may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The KK74ACT620 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.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA; 0.1 µA @ 25°C

• Outputs Source/Sink 24 mA
