HCF4538BEY Description

Short technical summary and product information.

The HCF4538BEY from STMicroelectronics is a monolithic integrated circuit dual precision monostable multivibrator. It is designed for stable retriggerable/resettable one-shot operation in various timing applications.

 

This device supports a wide supply voltage range from 3V to 20V and operates across an industrial temperature range of -55°C to 125°C. Key electrical characteristics include a propagation delay of 100ns and Schmitt trigger inputs, allowing for flexible input signal rise and fall times.

 

The HCF4538BEY is available in a 16-DIP package, suitable for through-hole mounting. It features two independent monostable circuits, each controlled by external resistor (RX) and capacitor (CX) components to set the output pulse width. The device also includes separate reset capabilities for immediate termination of output pulses.

 

This multivibrator is ideal for applications requiring precise timing control and stable pulse generation. Its robust design and wide operating parameters make it a versatile component for embedded systems and control circuits.
