The SN74ACT595-Q1 device contains an 8-bit, serial-in, parallel-out shift
register that feeds an 8-bit D-type storage register. The storage register has
parallel 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 register outputs are in a high-impedance state. Internal register
data is not impacted by the operation of the OE input.
