SLS SL74HC165D, SL74HC165N Datasheet

SL74HC165

Semiconductor

8-Bit Serial or Parallel-Input/
Serial-Output Shift Register

High-Performance Silicon-Gate CMOS

The SL74HC165 is identical in pinout to the LS/ALS165. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.

This device is an 8-bit shift register with complementary outputs
from the last stage. Data may be loaded into the register either in
parallel or in serial form. When the Serial Shift/ Parallel Load input is
low, the data is loaded asynchronously in parallel. When the Serial
Shift/Parallel Load input is high, the data is loaded serially on the rising
edge of either Clock or Clock Inhibit (see the Function Table).

The 2-input NOR clock may be used either by combining two
independent clock sources or by designating one of the clock inputs to
act as a clock inhibit.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA

• High Noise Immunity Characteristic of CMOS Devices
