This CLR input also serves as a trigger input when it is pulsed with a low level pulse transition.

The pin-out is identical to DM74LS but, functionally it is not. The output pulses can be terminated by the overriding clear.

Pulse triggering occurs at a voltage level and is not related to the transition time of the input pulse.

To obtain the best and trouble free operation from this device please read operating rules as well as the Fair- child Semiconductor one-shot application notes carefully and observe recommendations. Output pulse width may be varied from 35 nanoseconds to a maximum of 70 s by choosing appropriate timing components.

To obtain the best and trouble free operation from. The clear CLR input can terminate the output pulse at a predetermined time independent of the timing components. Jitter-free operation is maintained over the full temperature and VCC ranges for greater than six decades of timing capacitance 10 pF to 10 mFand greater than one decade of timing resistance 2. This provides the input with excellent noise immunity.
