... DM74LS123 Dual Retriggerable One-Shot with Clear and Complementary Outputs General Description The DM74LS123 is a dual retriggerable monostable multi- vibrator capable of generating output pulses from a few nano-seconds to extremely long duration up to 100% duty cycle. Each device has three inputs permitting the choice of either leading edge or trailing edge triggering ...

... When an electrolytic capacitor is used for C ing diode is often required for standard TTL one-shots to prevent high inverse leakage current. This switching diode is not needed for the DM74LS123 one-shot and should not be used. In general the use of the switching diode is not recommended with retriggerable operation. ...

... V to ground is necessary on each device. Fur- CC thermore, the bypass capacitor should be located as close to the V -pin as space permits. CC Note: For further detailed device characteristics and output per- formance please refer to the Fairchild Semiconductor one-shot application note AN-372. 3 and R must be kept pins (6) ...
