74LS121
Schematic symbol
Monostable multivibrator (one-shot): Makes a single output pulse each time it is triggered, with a length set by an external resistor and capacitor (or the built-in 2 kΩ resistor on Rint). It triggers on a falling edge on A1 or A2 while the other A input and B are high, or on a rising edge of B while A1 or A2 is low. The Schmitt-trigger B input also works with slow edges. Pins 2, 8, 12 and 13 are not connected.
