APPLICATION INFORMATION slow input rise fall times cause additional power dissipation. This calculated using following formula: ICC(AV) ICC(AV)) VCC. Where: additional power dissipation (µW); input frequency (MHz); input rise time (µs); 90%; input fall time (µs); 90%; ICC(AV) average additional supply current (µA). ICC(AV) differs with positive negative input transitions, shown Figs 74HC/HCT14 used relaxation oscillator circuit, Fig.18. Note application information values given typical unless otherwise specified.
