DESCRIPTION
The 74LVX594 is a low voltage CMOS 8 BIT
SHIFT REGISTER WITH OUTPUT REGISTER
fabricated with sub-micron silicon gate and
double-layer metal wiring C
ideal for low power, battery operated and low
noise 3.3V applications.
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 system. It combines
high speed performance with the true CMOS low
power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
