3 Description

The TPIC6C595 is a monolithic, medium-voltage,

low-current power 8-bitshift register designed for use

in systems that require relatively moderate load

power such asLEDs. The device contains abuilt-in

voltage clamp on the outputs for inductive transient

protection. Power driverapplications include relays,

solenoids, and otherlow-current or medium-voltage

loads.

This device contains an 8-bit serial-in, parallel-out

shift registerthat feeds an8-bit D-type storage

register. Data transfersthrough both the shift and

storage registersonthe risingedge ofthe shift

register clock(SRCK) and the register clock(RCK),

respectively. The device transfers data out the serial

output (SER OUT) port on the rising edge of SRCK.

The storage register transfers data to the output
