TPIC6273N Power Logic 8-Bit Shift Register

The TPIC6273N, by Texas Instruments, is a significant component designed to address the needs of systems requiring high-voltage, high-current, and low-power serial-to-parallel data conversion. This integrated circuit is part of the TPIC family of power logic devices and serves as an 8-bit shift register with output latches and control circuitry designed for driving highly inductive loads with high efficiency and speed.

Key Features:

• Voltage and Current Ratings: The device operates with a 5-V VCC and can sustain output voltages up to 50 V with output currents of 250 mA per channel, making it suitable for a wide range of applications.
• Power Output: It can deliver a continuous current of 250 mA for each of the 8 output channels, with a total power dissipation of 2 W, allowing it to drive multiple components simultaneously.
• Shift Register: The 8-bit shift register ensures efficient serial-to-parallel data conversion, which is essential for simplifying the data transmission process and reducing the number of required I/O pins.
• Built-in Clamp Diodes: Integrated clamp diodes provide protection against inductive kickback, which is particularly useful when driving inductive loads such as relays, solenoids, and motors.
• Enhanced Thermal Performance: The TPIC6273N comes in a PowerDIP package, which enhances thermal performance and ensures reliable operation even under high-current driving conditions.

Applications:

The TPIC6273N is versatile and can be used in a variety of applications, including:

• Relay driven displays
• LED displays
• Motor and solenoid control circuits
• Industrial controls
• Line drivers

With its robust design and powerful capabilities, the TPIC6273N from Texas Instruments is an excellent choice for designers looking to create efficient, high-performance systems that require reliable high-voltage and high-current handling capabilities.
