Product Introduction
The SN74LVC1G123 device is a single retriggerable monostable multivibrator designed for 1.65-V to 5.5 V CC operation.
This monostable multivibrator features output pulseduration control by three methods. In the first method, the A input is low, and the B input goes high. In the second method, the B input is high, and the A input goes low. In the third method, the A input is low, the B input is high, and the clear (CLR) input goes high.
The output pulse duration is programmed by selecting external resistance and capacitance values. The external timing capacitor must be connected between C ext and R ext/C ext (positive) and an external resistor connected between R ext/C ext and V CC. To obtain variable pulse durations, connect an external variable resistance between R ext/C ext and V CC. The output pulse duration also can be reduced by taking CLR low.
Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. The A and B inputs have Schmitt triggers with sufficient hysteresis to handle slow input transition rates with jitter-free triggering at the outputs.
