Texas Instruments CD74HC123NSR Counters and Dividers Overview
Dual retriggerable monostable multivibrator ICs, featuring two independent circuits for precise timing control. These high-speed CMOS logic devices operate from a 2V to 6V supply range, with a typical 5V operating voltage. They offer a 5.2mA output current capability at both high and low levels, and a propagation delay of 480ns.
Packaged in a 16-SOIC format with gold contact plating, these surface-mount components are RoHS compliant and suitable for operation between -55°C and 125°C.
