STMicroelectronics HCF4098BMTR Precision Monostable/Astable Multivibrator

The HCF4098BMTR is a highly versatile integrated circuit from STMicroelectronics, designed to function as either a precision monostable (one-shot) or astable (free-running) multivibrator. This dual in-line package is engineered to cater to a wide range of timing and pulse generation applications. It is a member of the CMOS family, which ensures low power consumption and high noise immunity.

Constructed with silicon gate C2MOS technology, the HCF4098BMTR provides a robust and reliable solution for designers looking to implement timing functions in their electronic circuits. Its features include two retriggerable/resettable monostable multivibrators, each with its own trigger and reset inputs. The retriggerable mode allows for pulse width to be extended with each new trigger pulse, while the reset function can terminate the output pulse at any time, providing excellent control over pulse durations.

The timing period for this multivibrator can be controlled using external resistors and capacitors, offering designers flexibility in setting the desired time constants. This feature makes it suitable for a wide range of applications, from pulse shaping and timing delay circuits to frequency division and precision timing tasks.

The HCF4098BMTR operates over a wide voltage range from 3V to 15V, making it compatible with both TTL and CMOS logic levels. This allows for easy integration into various system designs without the need for additional level-shifting components. The device is also characterized for operation from -55°C to 125°C, ensuring reliability and performance under extreme environmental conditions.

Available in a compact surface-mount package, the HCF4098BMTR is designed for space-constrained applications. Its small footprint and low profile make it an excellent choice for use in modern electronic devices where board space is at a premium.

In summary, the HCF4098BMTR from STMicroelectronics is a versatile and efficient solution for designers looking to incorporate precise timing functions into their electronic systems. With its wide operating voltage range, temperature stability, and flexible configuration options, it stands out as a valuable component in a variety of timing-related applications.
