SNx4HC595 8-Bit Shift Registers With 3-State Output Registers

1 Features

• 8-bit serial-in, parallel-out shift

• Wide operating voltage range of 2 V to 6 V

• High-current 3-state outputs can drive up to 15

LSTTL loads

• Low power consumption: 80-μA (maximum) ICC

• tpd = 13 ns (typical)

• ±6-mA output drive at 5 V

• Low input current: 1 μA (maximum)

• Shift register has direct clear

• On products compliant to MIL-PRF-38535,

all parameters are tested unless otherwise noted.

On all other products, production processing does

not necessarily include testing of all parameters.

2 Applications

• Network switches

• Power infrastructure

• LED displays

• Servers

3 Description

The SNx4HC595 devices contain an 8-bit, serial-in,

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

storage register. 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 serial outputs for cascading. When the

output-enable (OE) input is high, the outputs are in

the high-impedance state.
