PIN DESCRIPTIONS
INPUTS
A1, A2 (Pins 1, 2)
Serial Data Inputs. Data at these inputs determine the data
to be entered into the first stage of the shift register. For a
high level to be entered into the shift register, both A1 and A2
inputs must be high, thereby allowing one input to be used as
a data–enable input. When only one serial input is used, the
other must be connected to VCC.
Clock (Pin 8)
Shift Register Clock. A positive–going transition on this pin
shifts the data at each stage to the next stage. The shift
register is completely static, allowing clock rates down to DC
in a continuous or intermittent mode.
OUTPUTS
QA – QH (Pins 3, 4, 5, 6, 10, 11, 12, 13)
Parallel Shift Register Outputs. The shifted data is pres-
ented at these outputs in true, or noninverted, form.
CONTROL INPUT
Reset (Pin 9)
Active–Low, Asynchronous Reset Input. A low voltage ap-
plied to this input resets all internal flip–flops and sets Out-
puts QA – QH to the low level state.
