Overview
The TPIC2810DG4, produced by Texas Instruments, is a monolithic, medium-voltage, low-current, 8-bit shift register designed to drive low-side switched resistive loads such as LEDs. This device is not recommended for switching inductive loads. It features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, with data transfer facilitated through an I2C bus interface. The device includes internal power-up clear and thermal shutdown mechanisms for added protection.
