HIFT 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.

This device contains protection circuitry to guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of any voltage
higher than maximum rated voltages to this high-impedance circuit. For proper operation, V
IN
and
V
OUT
should be constrained to the range GND≤(V
IN
or V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or
V
CC
). Unused outputs must be left open.
