MM54C165/MM74C165
Parallel-Load 8-Bit Shift Register
General Description
The MM54C165/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 oc-
curs on the rising edge of CLOCK1 or CLOCK2. Clock in-
puts 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 dou-
ble-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.
