STMicroelectronics HCF40105BE 4-Bit x 4-Word FIFO Register

The HCF40105BE from STMicroelectronics is a high-quality, integrated circuit designed as a 4-bit by 4-word FIFO (First In First Out) register. This versatile component is crafted with precision to ensure reliable data storage and retrieval in a sequential manner, making it an essential building block for a wide variety of digital systems that require data buffering.

Constructed using silicon gate C2MOS technology, the HCF40105BE offers a robust and power-efficient solution for your electronic designs. Its primary function is to serve as a temporary storage device that allows data to be written into and read from its memory in a FIFO sequence. This ensures that the first data entered is the first to be retrieved, a critical feature for maintaining the order of data in applications such as data communication, processors, and digital signal processing.

The device features a 4-bit wide data path, which allows for the parallel processing of 4-bit chunks of data, enhancing the speed and efficiency of data handling. The 4-word depth provides sufficient buffer space for many applications while maintaining a compact form factor. With its simple and reliable interface, the HCF40105BE can be easily integrated into various digital systems.

Key specifications of the HCF40105BE include:

• Operating Voltage Range: 3V to 20V
• Low Power Consumption: Ensures energy efficiency in your designs
• Medium Speed Operation: 8MHz (typ.) at VDD = 10V
• Fully Static Operation: Provides stability and reliability in operation
• Standardized Symmetrical Output Characteristics
• 100% Tested for Quiescent Current at 20V
• Maximum Input Current of 1µA at 18V: Ensures minimal disturbance from input signals
• 5V, 10V, and 15V Parametric Ratings

The HCF40105BE is encapsulated in a 16-pin dual in-line package (DIP), which is widely used and easily handled in electronic circuits. Its compatibility with JEDEC standard no. 13B ensures that it can be replaced or integrated with other standard components without hassle. Whether you're designing a new system or upgrading an existing one, the HCF40105BE from STMicroelectronics is a reliable and efficient choice for your FIFO register needs.
