DESCRIPTION
The 74VHC594 is an high speed CMOS 8-BIT
SHIFT REGISTERS fabricated with sub-micron
silicon gate C2MOS technology.
This device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D-type storage
register. Separate clocks and direct overriding
clear (SCLR, RCLR) are provided for both the shift
register and the storage register.

A serial (QH’) output is provided for cascading
purposes. Both the shift register and storage
register use positive-edge triggered clocks. If the
clocks are connected together, the shift register
state will always be one clock pulse ahead of the
storage register.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V.
All inputs are equipped with protection circuits
against static discharge, giving them 2KV ESD
immunity and transient excess voltage.
