74LS Datasheet(PDF) – Fairchild Semiconductor

The clear CLR input can terminate the output. Not more than one output should be shorted at a time, and the duration should not exceed one second. Pulse triggering occurs datasheeg a voltage level and is not related to the transition time of the input pulse. Month Sales Transactions. Each device has three inputs permit. This mode of triggering requires first the B input be set from a.

Margin,quality,low-cost products with low minimum orders. Devices also available in Tape and Reel. Input pulse width dataseet be of any duration relative to the output pulse width.

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. This CLR input also serves as a trigger. Each device has three inputs permit- ting the choice of either leading-edge or trailing-edge trig- gering. Output pulse width may be varied from 35 nanoseconds to datashet maximum of 70 s by choosing appropriate timing components.

The pin-out is identical to DM74LS but, functionally it is not. The range of jitter-free pulse widths is extended if VCC is 5.

SeekIC only pays the seller after confirming you have received your order.

We will also never share your payment details with your seller. This provides the input with excellent noise immunity. Additionally an internal latching datasheett at the input stage also provides a high immunity to V CC noise. If pulse cutoff is not critical, capacitance up to mF and resistance as low as 1.

This CLR input also serves as a trigger input when it is pulsed with a low level pulse transition. This provides the input with. Input Current Max Input Voltage. The DM74LS is a dual monostable multivibrator with.
