Data Inputs
A, B, C, D, E, F, G, H (Pins 15, 1, 2, 3, 4, 5, 6, 7)
data latch on the rising edge of the Latch Clock input.
S
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.
Control Inputs
Serial Shift/Parallel Load (Pin 13)
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 data latch.
Shift Clock (Pin 11)
shifts data on the serial data input into the shift register and
A
Parallel data inputs. Data on these inputs are stored in the
Serial data input. Data on this input is shifted into the shift
Shift register mode control. When a high level is applied
Serial shift clock. A low-to-high transition on this input
