The ’HC595 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.

Both the shift register clock (RCLK) and storage
register clock (SRCLK) are positive-edge trig-
gered. If both clocks are connected together, the
shift register is always one clock pulse ahead of
the storage register.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.
