SN74HCS595 8-Bit Shift Register With Schmitt-Trigger Inputs and 3-State Output

Registers

1 Features

• Wide operating voltage range: 2 V to 6 V

• Schmitt-trigger inputs allow for slow or noisy input

signals

• Low power consumption

– Typical input leakage current of ±100 nA

• ±7.8-mA output drive at 6 V

• Extended ambient temperature range: –40°C to

2 Applications

• Output expansion

• LED matrix control

• 7-segment display control

• 8-bit data storage

3 Description

The SN74HCS595 device contains an 8-bit, serial-in,

parallel-out shift register that feeds an 8-bit D-type

storage register. All inputs include Schmitt-trigger

architecture, eliminating any erroneous data outputs

due to slow-edged or noisy input signals. 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 a serial output

input is high, the storage register outputs are in a

high-impedance state. Internal register data and serial

OE input.
