High–Performance Silicon–Gate CMOS
The MC54/74HC165A 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.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1
