TI SN74LV123ATPWRQ1

单稳态10.5 ns2 V ~ 5.5 V

Overview

The ’LV123A devices are dual retriggerable monostable multivibrators designed for 2-V to 5.5-V VCC operation.

The output pulse duration is programmable by selecting external resistance and capacitance values. The external timing capacitor must be connected between Cext and Rext/Cext (positive) and an external resistor connected between Rext/Cext and VCC. To obtain variable pulse durations, connect an external variable resistance between Rext/Cext and VCC. The output pulse duration also can be reduced by taking CLR low.
