Overview
The TPIC6273DW is a monolithic high-voltage, high-current power logic octal D-type latch with DMOS transistor outputs, designed by Texas Instruments. This device is tailored for systems that require relatively high load power, making it suitable for applications involving medium-current or high-voltage loads. The TPIC6273DW features eight positive-edge-triggered D-type flip-flops with a direct clear input and open-drain power DMOS transistor outputs. It includes a built-in voltage clamp on the outputs for inductive transient protection, ensuring robust operation in demanding environments.
