TPIC6595N

TPIC6595N Description

The TPIC6595N from Texas Instruments is an 8-bit power logic shift register designed for high-voltage, high-current applications. Housed in a 20-pin DIP (Through Hole) package, it integrates a serial-to-parallel conversion function with open-drain outputs, making it suitable for driving heavy loads such as relays, LEDs, and solenoids. Operating within a 4.5V to 5.5V supply range, this ROHS3-compliant device is classified under EAR99 and is REACH unaffected, ensuring compliance with global environmental standards. Its non-moisture-sensitive (MSL: Not Applicable) construction enhances reliability in industrial environments.

TPIC6595N Features

• 8-bit serial-in, parallel-out shift register with open-drain outputs for flexible load driving.
• High-voltage tolerant (up to 50V) outputs, enabling direct control of inductive or resistive loads.
• Low-power CMOS logic with TTL-compatible inputs for seamless integration into digital systems.
• Serial-to-parallel conversion with latch-enabled outputs for synchronized data transfer.
