3 Description
The SN74ACT596-Q1 device contains an 8-bit, serialin,
parallel-out shift register that feeds an 8-bit D-type
storage register. The storage register has parallel
open-drain outputs. Separate clocks are provided
for both the shift and storage register. The shift
register has a direct overriding clear (SRCLR) input,
serial (SER) input, and a serial output (QH') for
cascading. When the output-enable (OE) input is high,
the outputs are in a high-impedance state. Internal
register data is not impacted by the operation of the
OE input.
