Overview
The TPIC6595DWR from Texas Instruments is a monolithic, high-voltage, high-current power 8-bit shift register. It is designed for use in systems that require relatively high load power. The device features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, making it suitable for various power driver applications such as relays, solenoids, and other medium-current or high-voltage loads. The TPIC6595DWR includes built-in voltage clamps on the outputs for inductive transient protection and supports cascading of data to additional devices through its serial output (SER OUT).
