Output pulse width may be varied from 35 nanoseconds to a maximum of 70 s by choosing appropriate timing components.

This provides the input with excellent noise immunity. Month Sales Transactions. This CLR input also serves as a trigger. Additionally an internal latching circuit at the input 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 DM74LS is a dual monostable multivibrator with. Recent History What is this? V I Input Clamp Voltage. Freight and Payment Recommended logistics Recommended bank.

Additionally an internal latching. Not more than one output should be shorted at a time, and the duration should not exceed one second. We will also never share your payment details with your seller. Faithfully describe 24 hours delivery 7 days Changing or Refunding. Pulse triggering occurs at a voltage level and is not related to the transition time of the input pulse.

Devices also available in Tape and Reel. Input Current Max Input Voltage. 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. If pulse cutoff is not critical, catasheet up to mF and resistance as low as 1. Margin,quality,low-cost products with low minimum orders. Bonase Electronics HK Co. Schmitt-trigger input circuitry for B. A high immunity. The output.

Input pulse width. Output pulse. With R. Output rise. Pulse width is defined by the relationship:.
