September 1993 7 Philips Semiconductors Product specification Hex inverting Schmitt trigger 74HC/HCT14 APPLICATION INFORMATION The slow input rise and fall times cause additional power dissipation, this can be calculated using the following formula: Pad = fi x (tr x ICCa + tf x ICCa) x VCC. Where: Pad = additional power dissipation (W) fi = input frequency (MHz) tr = input rise time (s); 10% - 90% tf = input fall time (s); 10% - 90% ICCa = average additional supply current (A) Average ICCa differs with positive or negative input transitions, as shown in Figs 14 and 15. Fig.14 Average ICC for HC Schmitt trigger devices; linear change of Vi between 0.1 VCC to 0.9 VCC Fig.15 Average ICC for HCT Schmitt trigger devices; linear change of Vi between 0.1 VCC to 0.9 VCC.
