Overview
The TPIC6C596PW device, produced by Texas Instruments, is a monolithic, medium-voltage, low-current 8-bit shift register. It is designed for use in systems that require relatively moderate load power, such as driving LEDs, relays, solenoids, and other low-current or medium-voltage loads. The device features a built-in voltage clamp on the outputs for inductive transient protection and is characterized for operation over an operating case temperature range of -40°C to 125°C.
