3 Description
The SNx4HC595 devices contain an 8-bit, serial-in,
parallel-out shift register that feeds an 8-bit D-type
storage register. The storage register has parallel 3-
state 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 serial outputs for cascading. When the
output-enable (OE) input is high, the outputs are in
the high-impedance state.
