STMicroelectronics M74HC4538B1R Multivibrator
The M74HC4538B1R is a high-speed CMOS Dual Retriggerable Monostable Multivibrator fabricated with silicon gate C2MOS technology from STMicroelectronics. This integrated circuit is designed to generate precise and stable time delays or oscillation, making it an ideal choice for a wide array of applications such as timing, pulse shaping, and signal processing in digital systems.
With its retriggerable function, the M74HC4538B1R allows for the extension of the output pulse duration with each new trigger input pulse, providing flexibility and control in timing applications. The device has two monostable multivibrators (also known as 'one-shots') in a single package, each with its own set of inputs and outputs. This dual configuration enables the use of one IC for two independent timing sequences, saving space and reducing complexity in circuit designs.
The M74HC4538B1R operates with a wide supply voltage range from 2V to 6V, making it compatible with TTL, CMOS, and other logic families. Its low power consumption and high noise immunity are characteristic of the CMOS technology used in its manufacture, ensuring reliable operation even in challenging conditions.
Key features of the M74HC4538B1R include:
- Separate reset inputs for each multivibrator
- Leading-edge triggering (A) and trailing-edge triggering (B)
- Output pulse width range from nanoseconds to extremely long duration
- Output capability: standard
- ICCU: low
- Pin and function compatible with 4538 of the 4000B series
This product is offered in a DIP-16 package, ensuring ease of integration into a variety of circuit boards. The M74HC4538B1R is a versatile and reliable component, perfect for designers looking to implement precise timing functions without compromising on space or power efficiency. Whether used in control systems, communication devices, or complex data processing units, this multivibrator from STMicroelectronics stands out as a top choice for professionals in the electronics industry.
