74HC221 ,Dual Monostable Multivibrator , SOP-16, 2V-6V

The 74HC221 is a high-speed CMOS dual monostable multivibrator with Schmitt trigger inputs. It is designed to generate accurate, retriggerable pulse outputs based on external resistors and capacitors. The device operates over a wide voltage range of 2V to 6V, making it suitable for timing, pulse generation, and delay circuit applications. Each monostable section of the 74HC221 can be independently triggered by positive or negative transitions. The pulse duration is controlled via an external resistor and capacitor and can be extended via retriggering. The device is capable of high-noise immunity, ensuring stable operation in harsh environments. Encased in a SOP-16 surface-mount package, the 74HC221 is ideal for applications requiring precise timing control, frequency pulse shaping, and delay circuits.
