description/ordering information
The ’AHC595 devices contain an 8-bit serial-in,
parallel-out shift register that feeds an 8-bit D-type
storage register. The storage register has parallel
3-state outputs. Separate clocks are provided for
both the shift and storage registers. The shift
register has a direct overriding clear (SRCLR)
input, serial (SER) input, and a serial output for
cascading. When the output-enable (OE) input is
high, all outputs, except QH′, are in the
high-impedance state.
Both the shift-register clock (SRCLK) and
storage-register clock (RCLK) are positive-edge
triggered. If both clocks are connected together,
the shift register always is one clock pulse ahead
of the storage register.
