74VHC595
8-Bit Shift Register with Output Latches
General Description
The VHC595 is an advanced high-speed CMOS Shift Reg-
ister fabricated with silicon gate CMOS technology. It
achieves the high-speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation.
This device contains an 8-bit serial-in, parallel-out shift reg-
ister that feeds an 8-bit D-type storage register. The stor-
age register has eight 3-STATE outputs. Separate clocks
are provided for both the shift register and the storage reg-
ister. The shift register has a direct-overriding clear, serial
input, and serial output (standard) pins for cascading. Both
the shift register and storage register use positive-edge
triggered clocks. If both clocks are connected together, the
shift register state will always be one clock pulse ahead of
the storage register.
An input protection circuit insures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
