In most applications, pulse stability will only be limited by the accuracy of external timing components. Please create an account or Sign in. We will also never share your payment details with your seller.

Output rise and fall times are independent of pulse length. 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. SeekIC only ddatasheet the seller after confirming you have received your order. Margin,quality,low-cost products with low minimum orders.

Additionally an internal latching circuit at the input stage also provides a high immunity to V CC noise. Freight and Payment Recommended logistics Recommended datashset.

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

I CC Supply Current. The output pulses can be terminated by the overriding clear. Additionally an internal latching. To obtain the best and trouble free operation from. Recent History What is this? Input Current Max Input Voltage. Each device has three inputs permit.

Order Number Package Number. 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. The pin-out is identical to DM74LS but, functionally it is not.

This provides the input with excellent noise immunity. The clear CLR input can terminate the output. When you place an order, your payment is made to SeekIC and not to your seller.

The clear CLR input can terminate the output pulse at a predetermined time independent of the datasheer components. The 74l221 is a dual monostable multivibrator with. Devices also available in Tape and Reel. Each device has three inputs permit- ting the choice of either leading-edge or trailing-edge trig- gering. If pulse cutoff is not critical, capacitance up to mF and resistance as low as 1. Pulse width is defined by the relationship: This CLR input also serves as a trigger.
