STMicroelectronics HCF4098BE Integrated Circuit

The HCF4098BE is a versatile monolithic integrated circuit produced by STMicroelectronics, designed specifically for use in precision timing and pulse generation applications. This dual monostable multivibrator features a wide range of capabilities that make it an essential component for designers who require reliable timing solutions in their electronic projects.

The device consists of two independent monostable multivibrators, each capable of producing accurate time delays or oscillation. In the time delay mode, the time is precisely controlled by one external resistor and one capacitor. For astable operation, the frequency and duty cycle can be controlled independently with two external resistors and one capacitor.

The HCF4098BE operates over a broad voltage range from 3V to 18V and offers a high degree of stability, ensuring consistent performance over its entire voltage range. This makes it suitable for applications that may experience fluctuations in power supply, ensuring that the device remains reliable under varying conditions.

Key features of the HCF4098BE include:

• Wide supply voltage range (3V to 18V)
• High noise immunity characteristic of CMOS devices
• Low power consumption
• Direct reset input
• Output pulse width range from nanoseconds to extremely long duration up to 100% duty cycle
• Leading-edge triggering (A input) and trailing-edge triggering (B input)
• Retriggerable option for versatile pulse generation
• Output capability: standard (10mA)
• Temperature stability of 0.005% per °C

This integrated circuit is housed in a 16-pin dual-in-line package, making it easy to integrate into a variety of circuit boards and systems. The HCF4098BE's robust design ensures that it is capable of withstanding the rigors of everyday use in industrial, commercial, and consumer electronics applications.

Whether used in timing circuits, pulse generation systems, or as part of a more complex digital logic scheme, the HCF4098BE from STMicroelectronics provides the reliability and functionality needed to meet the demands of modern electronics design. Its precision and flexibility make it an invaluable tool for engineers and hobbyists alike who require consistent, accurate timing solutions.
