Input Current Max Input Catasheet. Pulse width is defined by the relationship: To obtain the best and trouble free operation from. This CLR input also serves as a trigger input when it is pulsed with a low level pulse transition.

DescriptionThe absolute maximum darasheet of the 74LS00N are: Pin A is an active-LOW trigger transition input and. I CC Supply Current. The pin-out is identical to DM74LS but, functionally it is not.

We will also never share your payment details with your seller. Month Sales Transactions.

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 dataasheet input. This provides the input with. SeekIC only pays the seller after confirming you have received your order.

Pulse triggering occurs at a voltage level and is not related to the transition time of the input pulse. Recent History What is this? Additionally datashest internal latching circuit at the input stage also provides a high immunity to V CC noise. The DM74LS is a dual monostable multivibrator with. The clear CLR input can terminate the output.

dattasheet Input pulse width may be of any duration relative to the output pulse width. Margin,quality,low-cost products with low minimum orders. Output pulse width may be varied from 35 nanoseconds to a maximum of 70 s by choosing appropriate timing components. In most applications, pulse stability will only be limited by the accuracy of external timing components.
