MC74HC165A
8−Bit Serial or
Parallel−Input/
Serial−Output Shift Register
High−Performance Silicon−Gate CMOS
http://onsemi.com
The MC74HC165A is identical in pinout to the LS165. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL 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.
