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
presented at these outputs in true, or noninverted, form.
CONTROL INPUT
Reset (Pin 9)
Active–Low, Asynchronous Reset Input. A low voltage
applied to this input resets all internal flip–flops and sets
Outputs QA – QH to the low level state.
