Overview
The TPIC6B273DWR is a monolithic, high-voltage, medium-current power logic octal D-type latch produced by Texas Instruments. This device is designed for use in systems that require relatively high load power and features eight positive-edge-triggered D-type flip-flops with direct clear inputs. Each flip-flop includes an open-drain power DMOS-transistor output, making it suitable for driving medium-current or high-voltage loads such as relays and solenoids. The device operates over a wide temperature range of –40°C to 125°C and includes built-in voltage clamps for inductive transient protection.
