low-current power 8-bit shift register designed for
use in systems that require relatively moderate
load power such as LEDs. The device contains a
built-in voltage clamp on the outputs for inductive
transient protection. Power driver applications
include relays, solenoids, and other low-current or
medium-voltage loads.

This device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D-type storage
register. Data transfers through both the shift and
storage registers on the rising edge of the shift
register clock (SRCK) and the register clock
(RCK), respectively. The storage register trans-
fers data to the output buffer when shift register
clear (CLR) is high. When CLR is low, all registers
in the device are cleared. When output enable (G)
is held high, all data in the output buffers is held
low and all drain outputs are off. When G is held

low, data from the storage register is transparent to the output buffers. When data in the output buffers is low,
the DMOS transistor outputs are off. When data is high, the DMOS transistor outputs have sink-current
capability. The serial output (SER OUT) is clocked out of the device on the falling edge of SRCK to provide
additional hold time for cascaded applications. This will provide improved performance for applications where
clock signals may be skewed, devices are not located near one another, or the system must tolerate
electromagnetic interference.
This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These
circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C,
Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated
voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device
should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriated logic voltage level,
preferably either V
or ground. Specific guidelines for handling devices of this type are contained in the publication Guidelines for
CC
Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.
