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. Margin,quality,low-cost products datadheet low minimum orders. This CLR input also serves as a trigger input when it is pulsed with a low level pulse transition.

This provides the input with. We will also never share your payment details with your seller. Each device has three inputs permit. Pin A is an active-LOW trigger transition input and. Dwtasheet provides the input with excellent noise immunity. The range of jitter-free pulse widths is extended if VCC is 5. The clear CLR input can terminate the output. Output rise and fall times are independent of pulse length. Freight and Payment Recommended logistics Recommended bank. Faithfully describe 24 hours delivery 7 days Changing or Refunding.

Jitter-free operation is maintained over the full temperature and Dafasheet ranges for greater than six decades of timing capacitance 10 pF to 10 mFand greater than one decade of timing resistance 2. The output pulses can be terminated by the overriding clear. The pin-out is identical to DM74LS but, functionally it is not. If pulse cutoff is not critical, capacitance up to mF and resistance as low as 1. This CLR input also serves as a trigger.

To obtain the best and trouble free operation from this device please read operating rules as dataaheet as the Fair- child Semiconductor one-shot application notes carefully and observe recommendations. Each multivibrator of the 74LS features a negative-transition-triggered input and a positive-transition-triggered input either of which can be used as an inhibit input.

Additionally an internal latching circuit at the input stage also provides a high immunity to V CC noise. A high immunity to VCC noise is also provided by internal latching circuitry.
