CD74HCT221E TI Dual Monostable Multivibrator | 16-PDIP | 4.5V-5.5V, 25ns

Product Overview

The CD74HCT221E is a high-speed CMOS dual monostable multivibrator from Texas Instruments, featuring two independent monostable circuits with Schmitt-trigger inputs. It is designed for use in pulse generation, timing, and delay applications. The device operates over a supply voltage range of 4.5V to 5.5V and is available in a 16-pin PDIP package. With typical propagation delays of 25ns and low power consumption, it is ideal for interfacing with TTL logic levels while maintaining CMOS advantages.
