STMicroelectronics HCF4094BFX: 8-Stage Shift-and-Store Bus Register

The HCF4094BFX from STMicroelectronics is a high-quality integrated circuit that serves as an 8-stage shift-and-store bus register. This device is part of the CMOS family and is designed to offer both high-speed operation and a robust storage solution for digital data. It operates on an extended voltage range, making it versatile for various applications.

This shift register features an 8-bit serial-in/parallel-out storage register that enables the conversion of serial data to parallel format. The HCF4094BFX is equipped with a storage register that allows the system to store the serial input data and present it in a parallel format. The parallel outputs can be connected directly to the bus lines or other data paths, which is particularly useful in microprocessor interfacing and digital control systems.

One of the salient features of the HCF4094BFX is its three-state output stage, designed to drive highly capacitive or relatively low-impedance loads. The three-state outputs ensure that multiple devices can be connected to a common bus without interference, as the output of a disabled device is effectively disconnected from the bus.

The device is also equipped with a clock input (CP) and an output-enable input (OE). The clock input governs the timing of the shifting operation, while the output-enable input controls the transition of the data from the storage register to the output bus. The HCF4094BFX also includes a data input (D) and a strobe input, which allows the user to store the data without transferring it to the output bus, providing additional flexibility in data handling.

Manufactured with silicon gate C2MOS technology, the HCF4094BFX ensures reliable operation and a reduced power consumption, which is critical for battery-powered and energy-efficient applications. The device is available in a variety of packages, including the standard DIP and SOP, making it suitable for both through-hole and surface-mount technology (SMT) configurations.

In summary, the STMicroelectronics HCF4094BFX is a versatile and efficient solution for digital data storage and transfer, perfect for applications requiring high-speed data acquisition, processing, and communication within electronic systems.
