TPIC6273 (ACTIVE) Octal D-type latch

Octal D-type latch - TPIC6273
Datasheet
 

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-edge-triggered 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 positive-going 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.
