The Texas Instruments CD74HC221NSR is a high-speed CMOS logic dual monostable multivibrator with reset. This integrated circuit features two independent monostable circuits, each capable of triggering from either the leading or trailing edge. The output pulse width is determined by an external resistor (RX) and capacitor (CX).
Key electrical specifications include a wide operating voltage range of 2V to 6V for HC types, with a supply current of 80µA. It offers a propagation delay of 18 ns and features push-pull outputs with IOL and IOH maximum currents of 5.2mA. The device operates over a temperature range of -55°C to 125°C.
Packaged in a 16-SOIC surface mount package, the CD74HC221NSR is suitable for various digital timing applications. It includes features like Schmitt trigger inputs on B inputs, buffered outputs (Q and Q\), and separate resets for each multivibrator. The high noise immunity and balanced propagation delay make it a reliable choice for digital designs.
