DESCRIPTION

SN54HC595...FK PACKAGE

(TOP VIEW)

The 'HC595 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.

Both the shift register clock (SRCLK) and storage

both clocks are connected together, the shift register

always is one clock pulse ahead of the storage
