74LVC1G123DCTRG4

74LVC1G123DCTRG4 from Texas Instruments is a Integrated Circuit Single retriggerable monostable multivibrator with Schmitt-trigger inputs - Pulse & delay generators. The SN74LVC1G123 device is a single retriggerable monostable multivibrator designed for 1.65V to 5.5V VCC operation. This monostable multivibrator features output pulse-duration 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 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. 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.
