The ’165 and ’LS165A are 8-bit serial shift

registers that shift the data in the direction of Q

toward Q when clocked. Parallel-in access to

SN54LS165A . . . FK PACKAGE

(TOP VIEW)

each stage is made available by eight individual,

direct data inputs that are enabled by a low level

at the shift/load (SH/LD) input. These registers

also feature gated clock (CLK) inputs and

complementary outputs from the eighth bit. All

inputs

are

diode-clamped

to minimize

20 19

transmission-line effects, thereby simplifying

system design.

Clocking is accomplished through a two-input

positive-NOR gate, permitting one input to be

used as a clock-inhibit function. Holding either of

the clock inputs high inhibits clocking, and holding

either clock input low with SH/LD high enables the

other clock input. Clock inhibit (CLK INH) should

be changed to the high level only while CLK is

high. Parallel loading is inhibited as long asSH/LD

is high. Data at the parallel inputs are loaded

directly into the register while SH/LD is low,

independently of the levels of CLK, CLK INH, or

serial (SER) inputs.
