| Features |
a negative-transition-triggered input and a positive-transition-triggered input either of which can be used as an inhibit input.
Pulse triggering occurs at a voltage level and is not related to the transition time of the input pulse. Schmitt-trigger input circuitry for B input allows jitter-free triggering for inputs as slow as 1 volt/ second, providing the circuit with excellent noise immunity. A high immunity to VCC noise is also provided by internal latching circuitry.
Once triggered, the outputs are independent of further transitions of the inputs and are a function of the timing component... |
