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 particular voltage level and is not directly related to the transition time of the input pulse. Schmitt-trigger input circuitry (TTL hysteresi
Applications
* pulse stability will only be limited by the accuracy of external timing components. Jitter-free
operation is maintained over the full temperature and VCC range for more than six decades of timing capacitance (10 pF to 10 µF) and more than one decade of timing resistance (2 kΩ to 100 kΩ). Throughou
