INVERTING SCHMITT TRIGGER
„ DESCRIPTION
The U74AHC3G14 is a high-speed inverting Schmitt trigger.
The U74AHC3G14 provides three inverting buffers with the action
of Schmitt trigger. The trigger is capable of transforming slowly
changing input signals into sharply defined, jitter-free output signals.
„ FEATURES
* Low power supply 1.0 μA at 5.5V
* Wide supply voltage range from 2V to 5.5V
* Up to 5.5V inputs accept voltages
* Max tPD of 8.6 ns at VCC = 5.0V, CL = 15pF
* Symmetrical output impedance
* High noise immunity
* Balanced propagation delays
„ APPLICATION
* Astable multivibrators
* Monostable multivibrators
* Wave and pulse shapers

Note: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
