Overview
The TPIC6C595N is a monolithic, medium-voltage, low-current power 8-bit shift register designed by Texas Instruments. This device is tailored for systems requiring relatively moderate load power, such as LEDs, relays, solenoids, and other low-current or medium-voltage loads. It features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, enabling efficient data transfer and control. The device includes built-in voltage clamps on the outputs for inductive transient protection, making it suitable for a variety of power driver applications.
