onsemi MC14094BCPG: 8-Stage Shift-and-Store Register IC

In the realm of digital logic and data management, shift registers play a pivotal role in applications ranging from data storage to serial-to-parallel conversion. The onsemi MC14094BCPG stands out as a robust and versatile integrated circuit (IC) designed to handle such tasks with efficiency and reliability. This 8-stage shift-and-store register offers a blend of functionality and performance, making it a preferred choice for engineers and designers working on complex digital systems.

The MC14094BCPG is part of the 4000 series CMOS logic family, renowned for its low power consumption and wide operating voltage range. This IC features eight synchronous serial-in, parallel-out stages, allowing it to efficiently manage data flow in sequential logic circuits. Each stage consists of a master-slave flip-flop, ensuring stable data transfer and storage. The device operates with a serial data input (DS), a clock input (CP), and an output enable (OE) pin, providing precise control over data shifting and output states.

One of the key attributes of the MC14094BCPG is its storage register capability. Unlike basic shift registers, this IC includes a separate storage latch for each stage. This means that data can be shifted in serially while the stored data remains unchanged until the user triggers a transfer. This feature is particularly useful in applications where data must be updated without disrupting the current output, such as in display drivers or LED matrices.

The IC also supports asynchronous master reset (MR), allowing all stages to be cleared simultaneously regardless of the clock state. This ensures immediate initialization when needed, enhancing system responsiveness. Additionally, the MC14094BCPG offers three-state outputs, enabling bus-oriented applications where multiple devices share a common data bus. The high-noise immunity and buffered inputs further contribute to its reliability in noisy environments.

With an operating voltage range of 3V to 18V, the MC14094BCPG is suitable for both low-voltage and industrial-level applications. Its low power dissipation makes it ideal for battery-operated devices, while its robust design ensures longevity in demanding conditions.

ICGOODFIND: The onsemi MC14094BCPG is a highly functional 8-stage shift-and-store register IC that excels in data management, serial-to-parallel conversion, and output control. Its combination of synchronous shifting, separate storage latches, and three-state outputs makes it invaluable for digital systems, from consumer electronics to industrial automation.
