TPIC6273N

The TPIC6273N is a monolithic high-voltage high-current power logic octal D 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.
