3 Description

The SN74HCS596 device contains an 8-bit, serial-in,

parallel-out shift register that feeds an 8-bit D-type

storage register. All inputs include Schmitt-triggers,

eliminating any erroneous data outputs due to slowedged

or noisy input signals. 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 highimpedance state. Internal

register data is not impacted by the operation of the

OE input.
