Part Number : 54LS123
Function : RETRIGGERABLE MONOSTABLE MULTIVIBRATOR
Package : DIP 16 Pin Type
Maker : Motorola , Freescale
Pinouts : 
Description :
Thesedc triggered multivibrators feature pulse width controlby three methods.The basic pulse width is programmed by selection of external resistance andcapacitance values.
The LS122 has an internal timing resistor that allows thecircuits to be used with only an external capacitor. Once triggered, the basic pulse width may be extended by retriggering the gated low-level-active (A) or high-level-active (B) inputs, or be reduced by use of the overriding clear.
