NXP HEF4094BT 8-stage Shift-and-Store Bus Register

The NXP HEF4094BT is a high-performance, 8-stage shift-and-store bus register designed to provide efficient serial-to-parallel data conversion with storage. Integrated into a compact SO16 package, this versatile IC is perfect for applications that require the acquisition and manipulation of serial data before interfacing with parallel input devices or microcontrollers.

This device operates on a wide voltage range from 3 V to 15 V, making it suitable for various digital logic applications. The HEF4094BT is a part of the HEF4000 family, well-known for its robustness and compatibility with industry-standard requirements.

The IC features a serial input (DS), eight parallel outputs (Q0 to Q7), a shift register clock input (CP), and a storage register clock input (STROBE). The shift register and storage register have separate clocks, which allows for flexibility in control and timing of data capture and transfer.

One of the key functionalities of the HEF4094BT is its ability to transfer data from the shift register to the storage register on a positive-going transition of the STROBE input. Data in the storage register appears at the outputs whenever the output-enable input (OE) is LOW. When OE is HIGH, the outputs are in a high-impedance OFF-state, which is particularly useful in bus-oriented applications.

The versatility of the HEF4094BT makes it an excellent choice for a wide range of applications, such as:

• Serial-to-parallel data conversion
• Control systems
• LED displays and indicators
• Data routing
• Interface circuitry
• Signal processing

With its capability to interface with microprocessors and its ease of use in expanding input/output lines, the HEF4094BT is a practical component for designers looking to optimize their digital circuit designs.

The NXP HEF4094BT is not only functional but also reliable, offering static protection and latch-up performance that meets or exceeds 100 mA per JESD78, ensuring the device's integrity during adverse conditions.

Overall, the HEF4094BT from NXP is a versatile and reliable choice for designers who require a high-quality shift-and-store bus register for their digital applications.
