description

The TPIC6B595 is a monolithic, high-voltage,

medium-current power 8-bit shift register

designed for use in systems that require relatively

high load power. The device contains a built-in

voltage clamp on the outputs for inductive

transient protection. Power driver applications

include relays, solenoids, and other mediumcurrent

or high-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

transfers data to the output buffer when shiftregister

clear (SRCLR) is high. When SRCLR is

low, the input shift register is 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 DMOStransistor

outputs have sink-current capability.

The serial output (SER OUT) allows for cascading

of the data from the shift register to additional

devices.
