Pulse triggering occurs at a voltage datassheet and is not related to the transition time of the input pulse. DescriptionThe absolute maximum ratings of the 74LS00N are: You may also be interested in: This CLR input also serves as a trigger. This mode of triggering requires first the B input be set from a. Output rise and fall times are independent of pulse length.

This provides the input with excellent noise immunity. The output pulses can be terminated by the overriding clear. SeekIC only pays the seller after confirming you have received your order. 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.

We will also never share your payment details with your seller. If pulse cutoff is not critical, capacitance up to mF and resistance as low as 1. Input pulse width may be of any duration relative to the output pulse width. Additionally daatsheet internal latching. Month Sales Transactions. I OS Short Circuit. To obtain the best and trouble free operation from.

V I Input Clamp Voltage. This CLR input also serves as a trigger input when it is pulsed with a low level pulse transition.

This provides the input with. Datzsheet Number Package Number. 74lls221 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. The DM74LS is a dual monostable multivibrator with. Margin,quality,low-cost products with low minimum orders. Pin A is an active-LOW trigger transition input and. Additionally an internal latching circuit at the datasheft stage also provides a high immunity to V CC noise.


In most applications, pulse stability will only be limited by the accuracy of external timing components. The dataasheet is identical to DM74LS but, functionally it is not. 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.

Freight and Payment Recommended logistics Recommended bank. Devices also available in Tape and Reel. The range of jitter-free pulse widths is extended if VCC is 5.

The clear CLR input can terminate the output pulse at a predetermined time independent of the timing components. Each device has three inputs permit. When you place an order, your payment is made to SeekIC and not to your seller. I CC Supply Current. Not more than one output should be shorted at a time, and the duration should datashet exceed one second.
