TPIC6C595DRG4 Power Logic 8-Bit Shift Register by Texas Instruments

The TPIC6C595DRG4 is a high-performance, 8-bit shift register designed and manufactured by Texas Instruments (TI). This integrated circuit is part of the TPIC6C595 family, which is known for its robust power logic performance and is ideal for applications requiring the serial to parallel conversion with high-voltage output drive capability. It is especially well-suited for driving LEDs, relays, and other high-current loads.

This device incorporates an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. In the output stage, eight regulated current sink drivers deliver 100 mA of continuous current to each channel, with a typical output voltage of 33V and 250 mA clamp diodes on the outputs for inductive transient suppression.

The TPIC6C595DRG4 offers enhanced functionality with its built-in features. It has a low power consumption with a typical shift register power supply current of 20 µA and a storage register power supply current of 200 µA. The device also has a wide operating voltage range from 4.5V to 5.5V, making it versatile for various power environments.

The shift register is clocked on the rising edge of the shift register clock input (SRCK), and the storage register has a separate clock input (RCK) for maximum flexibility. Data can be output in a cascading format by connecting the serial output (SER OUT) of one device to the serial input (SER IN) of the next device. This makes the TPIC6C595DRG4 an excellent choice for applications requiring the extension of serial communication without compromising output power.

The TPIC6C595DRG4 comes in a surface-mount SOIC (D) 16-pin package, ensuring a compact footprint for space-constrained applications. Its industrial-grade design guarantees reliable operation in a temperature range of -40°C to 125°C, making it suitable for harsh environments.

With its combination of high-voltage output, low power consumption, and robust design, the TPIC6C595DRG4 from Texas Instruments is an optimal solution for designers looking to efficiently manage power distribution in their digital systems.
