description/ordering information
The ’AHCT595 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
the shift and storage registers. The shift register
has a direct overriding clear (SRCLR) input, serial
(SER) input, and serial outputs for cascading.
When the output-enable (OE) input is high, the
outputs 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.
