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) I

• t

= 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

• 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.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

6.2 ESD Ratings

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) All unused inputs of the device must be held at V

or GND to ensure proper device operation. See the TI application report,

Implications of Slow or Floating CMOS Inputs, SCBA004.

(2) If this device is used in the threshold region (from V

max = 0.5 V to V

min = 1.5 V), there is a potential to go into the wrong state

from induced grounding, causing double clocking. Operating with the inputs at t

= 1000 ns and V

= 2 V does not damage the device;

however, functionally, the CLK inputs are not ensured while in the shift, count, or toggle operating modes.
