DESCRIPTION

The M74HC595 is an high speed CMOS 8-BIT
SHIFT REGISTERS/OUTPUT LATCHES
(3-STATE) fabricated with silicon gate C

2

MOS
technology.
This device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D -t y pe storage
register. The storage register has 8 3-STATE
outputs. Separate clocks a re provided for both t he
shift register and the storage register.

PIN CONNECTION AND IEC LOGIC SYMBOLS

The shift register has a direct-overriding clear,
serial input, and serial output (st andard) pins for
cascading. Both the shift register and storage
register use positive-edge t riggered clocks. If both
clocks are c onnec ted together, the shift r egister
state wi ll always be one clock pulse ahead of the
storage register.
All inputs a re equipped with protection circuits
against static discharge and transient excess
voltage.
