CD74HC4538MT TI Monostable Multivibrator | 16-SOIC | 2V-6V, 5MHz

Product Overview

The CD74HC4538MT from Texas Instruments is a high-speed CMOS dual monostable multivibrator with reset. It is designed for use in a wide range of timing and pulse generation applications. The device features two independent monostable multivibrators with Schmitt-trigger inputs for noise immunity. Each multivibrator can be triggered by either the rising or falling edge of the input signal, and the output pulse width is controlled by external resistors and capacitors. The CD74HC4538MT is offered in a 16-pin SOIC package and operates over a supply voltage range of 2V to 6V, making it suitable for battery-powered and low-voltage systems.
