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

clear (SCLR, RCLR) are provided for both the shift

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

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.
