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.
