TPIC6273
TPIC6273 is POWER LOGIC OCTAL D-TYPE LATCH manufactured by Texas Instruments.
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.
