INPUTS:

A, B, C, D, E, F, G, H - Parallel data inputs. Data on

these inputs is stored in the input latch on the rising

edge of the Latch Clock input.

SA - Serial data input. Data on this input is shifted into

the shift register on the rising edge of the Shift Clock

input if Serial Shift/Parallel Load is high. Data on this

input is ignored when Serial Shift/

Parallel Load is low.

SERIAL SHIFT/PARALLEL LOAD - Shift register

mode control. When a high level is applied to this pin,

the shift register is allowed to serially shift data. When

a low level is applied to this pin, the shift register

accepts parallel data from the input latch, and serial

shifting is inhibited.

RESET - Asynchronous, Active-low shift register

reset. A low level applied to this input resets the shift

register to a low level, but does not change the data in

the input latch.

SHIFT CLOCK - Serial shift register clock. A low-to-

high transition on this input shifts data on the Serial

Data Input into the shift register and data in stage H is

shifted out QH, being replaced by the data previously

stored in stage G.

LATCH CLOCK - A low-to-high transition on this

input loads the parallel data on inputs A -H into the

input latch.

OUTPUT:

QH - Serial data output. This pin is the output from the

last stage of the shift register.
