STPIC6C595

The STPIC6C595 is a high-performance 8-bit serial-in, parallel-out shift register manufactured by STMicroelectronics. It features a wide operating voltage range from 2.0V to 5.5V, making it suitable for various low-power and standard-voltage applications. The device employs CMOS technology, ensuring low static power consumption and high noise immunity, which enhances reliability in electrically noisy environments. This integrated circuit includes a storage register that captures data from the shift register on the rising edge of the latch clock (ST_CP). It supports serial data input (DS) and a shift clock (SH_CP), enabling efficient data transfer from external microcontrollers or logic circuits. With an output enable pin (OE), the STPIC6C595 allows precise control over output states, enabling active-low or tri-state outputs depending on system requirements. Its open-drain output configuration provides flexibility in driving loads such as LEDs, relays, or other digital components without additional level-shifting circuitry. The STPIC6C595 is widely used in applications requiring multiplexed I/O expansion, including LED displays, keyboard matrix interfaces, and industrial control systems. Its ability to reduce microcontroller pin usage makes it ideal for embedded designs where pin count is limited but multiple outputs are needed. The device also offers a high-speed operation with propagation delays under 30ns at 5V supply, ensuring responsive performance in real-time systems. Designed for robustness and ease of integration, the STPIC6C595 operates reliably across a broad temperature range from -40°C to +85°C, suitable for both commercial and industrial environments. It is available in standard 16-pin DIP and SO packages, facilitating easy PCB layout and automated assembly processes. Additionally, its compatibility with TTL-level inputs simplifies interfacing with common microprocessors and logic families, minimizing design complexity. In summary, the STPIC6C595 delivers efficient data handling, low power consumption, and reliable performance in diverse electronic systems, particularly where scalable I/O expansion and minimal component count are critical design goals.
