description

The TPIC6273 is a monolithic high-voltage

high-current power logic octal D-type latch with

DMOS transistor outputs 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 medium-current or high-voltage loads.

The TPIC6273 contains eight positive-edgetriggered

D-type flip-flops with a direct clear input.

Each flip-flop features an open-drain power

DMOS transistor output.

When clear (CLR) is high, information at the D

inputs meeting the setup time requirements is

transferred to the DRAIN outputs on the positivegoing

edge of the clock pulse. Clock triggering

occurs at a particular voltage level and is not

directly related to the transition time of the

positive-going pulse. When the clock input (CLK)

is at either the high or low level, the D input signal

has no effect at the output. An asynchronous CLR

is provided to turn all eight DMOS-transistor

outputs off.

The TPIC6273 is characterized for operation over

the operating case temperature range of –40°C

to 125°C.
