Overview
The Texas Instruments SN74LVC1G123DCUTG4 is a single retriggerable monostable multivibrator with Schmitt-trigger inputs. This device is designed to operate over a wide supply voltage range from 1.65 V to 5.5 V, making it versatile for various applications. It features a retriggerable monostable multivibrator that can be triggered from active-high or active-low gated logic inputs and supports up to 100% duty cycle from retriggering. The device also includes a clear input to terminate the output pulse early and has glitch-free power-up reset on all outputs.
