STPIC6C595M Power Logic 8-bit Shift Register

The STPIC6C595M is a high-voltage, high-current integrated circuit from STMicroelectronics designed to provide an efficient interface between low-level logic circuitry and high-power loads. This 8-bit shift register is part of STMicroelectronics' Power Logic series, which is renowned for its robust performance in various applications.

Manufactured with BiCMOS technology, the STPIC6C595M is capable of withstanding voltages up to 33V on the output pins, making it suitable for driving a wide range of devices, including LEDs, relays, and motors. The device integrates 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 sources allow the STPIC6C595M to provide a constant current to the loads, enhancing the consistency and reliability of the device's performance.

The shift register and storage register have separate clocks. Data is written to the shift register on the rising edge of the serial clock (SRCK), while the storage register is updated on a rising edge of the register clock (RCK). This allows for precise control of the timing of the output changes, which is critical in many high-speed applications.

One of the key features of the STPIC6C595M is its enhanced system reliability. The device includes an output enable (G) pin, which can be used to disable the outputs, thus providing a means to reduce power consumption or to enter a high-impedance state during power-up. Additionally, the STPIC6C595M is equipped with a clear (CLR) function that resets the internal shift register and storage register to the low state, ensuring a known startup state.

The STPIC6C595M is available in a SO-16N narrow package, which is optimized for space-constrained applications. Its operating temperature range from -40°C to +125°C, along with its robust output current and voltage handling capabilities, make it an ideal choice for automotive, industrial, and consumer applications where reliable high-voltage and high-current operation are required.
