Pulse width is defined by the relationship: Recent History What is this? Not more than one output should be shorted at a time, and the duration should not exceed one second. Jitter-free operation is maintained 47ls221 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. Order Number Package Number.


Additionally an internal latching. This provides the input with excellent noise immunity. SeekIC only pays the seller after confirming you have received your order.

Input pulse width may be of any duration relative to the output pulse width. Pulse triggering occurs at a voltage level and is not related to the transition time of the input pulse. Month Sales Transactions. The clear CLR input can terminate the output pulse at a predetermined time independent of the timing components.

The pin-out is identical to DM74LS but, functionally it is not. V I Input Clamp Voltage. Output pulse width may be varied from 35 nanoseconds to a maximum of 70 s by choosing appropriate timing components. Each device has three inputs permit. To obtain the best and trouble free operation from. Freight and Payment Recommended logistics Recommended bank. 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. 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.
