Overview
The TPIC6C595DRG4, produced by Texas Instruments, is a monolithic, medium-voltage, low-current power 8-bit shift register. This device is designed for use in systems that require relatively moderate load power, such as driving LEDs, relays, and solenoids. 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 over multiple outputs.
The device operates within a voltage supply range of 4.5 V to 5.5 V and is characterized for operation over a case temperature range of −40°C to 125°C. It includes built-in voltage clamps on the outputs for inductive transient protection, making it suitable for a variety of power driver applications.
