MC74HC165A
8âBit Serial or
ParallelâInput/
SerialâOutput Shift Register
HighâPerformance SiliconâGate CMOS
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 8âbit 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 2âinput 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.
