STMicroelectronics HCF4094BEY: 8-Stage Shift-and-Store Bus Register

The HCF4094BEY is a high-quality integrated circuit produced by STMicroelectronics, designed to provide efficient and reliable performance in a wide range of digital applications. This 8-stage shift-and-store bus register is part of the CMOS family and is well-suited for interfacing with the serial data of microprocessors and other digital systems.

With its versatile nature, the HCF4094BEY offers several key features that make it an essential component for developers and engineers. It operates with an 8-bit serial-in, parallel-out shift register that incorporates a storage register and 3-state outputs. This allows the device to convert serial input data into parallel output format, providing a seamless integration for systems requiring data manipulation and storage.

The device operates over a broad voltage range from 3V to 15V and provides low power TTL compatibility, ensuring that it can be used in low power systems as well as in environments with varying supply voltages. It also offers a high noise immunity characteristic of CMOS devices, which is crucial for maintaining signal integrity in noisy electronic environments.

One of the notable functionalities of the HCF4094BEY is its ability to transfer data from the shift register to the storage register on a positive-going transition of the clock input. Moreover, the device is capable of driving the bus line in a 3-state output configuration during the read-write selection mode. This makes it particularly useful in bus-oriented systems where multiple devices need to communicate over the same channel.

STMicroelectronics has packaged the HCF4094BEY in a DIP16 package, making it convenient for use in breadboards and prototyping, as well as in final production hardware. The robustness of the package ensures that the device can withstand the rigors of both development and operational environments.

In summary, the HCF4094BEY from STMicroelectronics is a versatile, reliable, and essential component for digital systems requiring efficient data transfer and storage. Its ability to interface with various microprocessors, low power consumption, and noise immunity makes it a top choice for designers and engineers in the electronics industry.
