Output pulse width may be varied from 35 nanoseconds to a maximum of 70 s by choosing appropriate timing components.

This mode of triggering requires first the B input be set from a. If pulse cutoff is not critical, capacitance up to mF and resistance as low as 1. 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.

A high immunity to VCC noise is also provided by internal latching circuitry.

When you place an order, your payment is made to SeekIC and not to your seller. This provides the input with. Jitter-free operation is maintained over the full temperature and VCC ranges for 74ls21 than six decades of timing capacitance 10 pF to 10 mFand greater than one decade of timing resistance 2.


The clear CLR input can terminate the output pulse at a predetermined time independent of the timing components. Each device has three inputs permit- ting the choice of either leading-edge or trailing-edge trig- gering. The range of jitter-free pulse widths is extended if VCC is 5. The clear CLR input can terminate the output.

Devices also available in Tape and Reel. Pulse width is defined by the relationship: Faithfully describe 24 hours delivery 7 days Changing or Refunding. The output pulses can be terminated by the overriding clear.
