8 / 8 page September 1993 8 Philips Semiconductors Product specification Quad 2-input NAND Schmitt trigger 74HC/HCT132 Application information The slow input rise and fall times cause additional power dissipation, this can be calculated using the following formula: Pad =fi × (tr × ICCa + tf × ICCa) × VCC. Where: Average ICCa differs with positive or negative input transitions, as shown in Figs 14 and 15. Pad fi tr tf ICCa = additional power dissipation ( µW) = input frequency (MHz) = input rise time (ns); 10% − 90% = input fall time (ns); 10% − 90% = average additional supply current ( µA) 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. HC/HCT132 used in a relaxation oscillator circuit, see Fig.16. Note to Application information All values given are typical unless otherwise specified. PACKAGE OUTLINES See “74HC/HCT/HCU/HCMOS Logic Package Outlines”.
