The Texas Instruments CD74HC221M is a high-speed CMOS dual monostable multivibrator with reset. This logic IC features two independent circuits, each capable of generating a precisely timed output pulse controlled by external resistor and capacitor components. It operates within a wide voltage range of 2V to 6V and utilizes HC technology for high noise immunity.
The CD74HC221M offers a propagation delay of 18 ns, making it suitable for timing applications requiring fast response. The device supports standard CMOS input types and push-pull output types. It is available in a 16-SOIC surface mount package, designed for efficient integration into electronic circuits.
Key features include a Schmitt trigger input on the B inputs for improved noise rejection and separate reset pins for each multivibrator. The output pulse width is determined by external R and C components, allowing for flexible timing configurations. This component is designed for a wide operating temperature range of -55°C to 125°C.
