DESCRIPTION The 74HC14 and 74HCT14 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC14 and 74HCT14 provide six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; Σ(CL × VCC2 × fo) = sum of the outputs. 2. For type 74HC14 the condition is VI = GND to VCC. For type 74HCT14 the condition is VI = GND to VCC − 1.5 V.

This can be calculated using the following formula: Pad = fi × (tr × ICC(AV) + tf × ICC(AV)) × VCC. Where: Pad = additional power dissipation (µW); fi = input frequency (MHz); tr = input rise time (µs); 10% to 90%; tf = input fall time (µs); 10% to 90%; ICC(AV) = average additional supply current (µA). ICC(AV) differs with positive or negative input transitions, as shown in Figs 16 and 17. For 74HC/HCT14 used in a relaxation oscillator circuit, see Fig.18.
