TECHNICAL DATA
8-Bit Serial-Input/Parallel-Output
Shift register
High-Speed Silicon-Gate CMOS
IN74ACT164
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
