IN74ACT164

8-BIT SERIAL-INPUT/PARALLEL-OUTPUT

SHIFT REGISTER

High-Speed Silicon-Gate CMOS

The IN74ACT164 is identical in pinout to the LS/ALS164,

HC/HCT164. The IN74ACT164 may be used as a level converter

for interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The IN74ACT164 is an 8-bit, serial-input to parallel-output shift

register. Two serial data inputs, A1 and A2, are provided so that

one input may be used as a data enable. Data is entered on each

rising edge of the clock. The active-low asynchronous Reset

overrides the Clock and Serial Data inputs.

• 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
