3 Description

The SN74AC596-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.
