CD74HC221E TI Monostable Multivibrator | 16-PDIP | Dual, 2V-6V, 5MHz

Product Overview

The CD74HC221E from Texas Instruments is a dual monostable multivibrator featuring high-speed CMOS technology. It is designed for pulse generation and timing applications, offering two independent multivibrators in a single 16-pin PDIP package. Each multivibrator can be triggered by either rising or falling edges, providing flexibility in system design. The device operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. With a typical propagation delay of 13 ns and output rise/fall times of 6 ns, it delivers reliable performance for high-frequency timing circuits.
