STMicroelectronics HCF4508BE Dual 4-Bit Latch

The HCF4508BE from STMicroelectronics is a high-performance integrated circuit that features dual 4-bit latches with separate strobe (enable) inputs for each latch. This versatile component is designed to be used in a wide range of electronic applications where data storage, signal buffering, or data transfer operations are required. Manufactured using silicon gate C2MOS technology, the HCF4508BE ensures reliable operation and low power consumption, making it an ideal choice for battery-operated devices and power-sensitive applications.

Each 4-bit latch within the HCF4508BE is capable of storing four bits of information, which can be accessed independently via the separate strobe inputs. When the strobe input is held high, the latch is transparent, and the data on its inputs is immediately reflected on the outputs. When the strobe input is taken low, the data present on the inputs at that moment is latched and held steady on the outputs, regardless of any subsequent changes on the input lines.

Key features of the HCF4508BE include:

• Medium-speed operation: typical clock timing of 40MHz at 10V
• Wide operating voltage range: 3V to 20V
• High noise immunity characteristic of C2MOS technology
• Low power consumption: 100nA typical at 18V and 25°C
• Standardized symmetrical output characteristics
• Complies with JEDEC standard no. 7A
• ESD protection: HBM > 2KV, MM > 200V

With its dual-latch configuration, the HCF4508BE provides flexibility in data management and control systems. It is commonly used in applications such as registers, buffers, rail-to-rail memory, and as a holding device for multiplexed systems. The HCF4508BE comes in a 16-pin dual in-line package (DIP), making it easy to integrate into both prototyping and production environments.

Whether you're designing a complex microprocessor system or a simple logic control circuit, the HCF4508BE offers the reliability and functionality needed to meet your design requirements. STMicroelectronics' commitment to quality ensures that this dual 4-bit latch will perform to the highest standards, providing a robust solution for your electronic projects.
