3 Description

The SN74ACT595-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

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.
