MM74C165
Parallel-Load 8-Bit Shift Register
General Description
The MM74C165 functions as an 8-bit parallel-load, serial
shift register. Data is loaded into the register independent
of the state of the clock(s) when PARALLEL LOAD (PL) is
low. Shifting is inhibited as long as PL is low. Data is
sequentially shifted from complementary outputs, Q
7
and
Q
7
, highest-order bit (P7) first. New serial data may be
entered via the SERIAL DATA (Ds) input. Serial shifting
occurs on the rising edge of CLOCK1 or CLOCK2. Clock
inputs may be used separately or together for combined
clocking from independent sources. Either clock input may
be used also as an active-low clock enable. To prevent
double-clocking when a clock input is used as an enable,
the enable must be changed to a high level (disabled) only
while the clock is HIGH.
