1. General description

The 74HC2G14; 74HCT2G14 is a dual inverter with Schmitt-trigger inputs. Inputs include

clamp diodes. This enables the use of current limiting resistors to interface inputs to

voltages in excess of V

. Schmitt trigger inputs transform slowly changing input signals

into sharply defined jitter-free output signals.

2. Features and benefits

Application information The slow input rise and fall times cause additional power dissipation, this can be calculated using the following formula: Padd = fi  (tr  ICC(AV) + tf  ICC(AV))  VCC where: Padd = additional power dissipation (W); fi = input frequency (MHz); tr = input rise time (ns); 10 % to 90 %; tf = input fall time (ns); 90 % to 10 %; ICC(AV) = average additional supply current (A).
