2 FETURES pplications: Wave and pulse shapers stable multivibrators Monostable multivibrators. Complies with JEDEC standard no. 7 ESD protection: HBM EI/JESD exceeds 2000 V MM EI/JESD exceeds 200 V. Specified from 40 to +85 C and 40 to +125 C. 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. 7. 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.

17 PPLICTION INFORMTION The slow input rise and fall times cause additional power dissipation. This can be calculated using the following formula: P ad =f i (t r I CC(V) +t f I CC(V) ) V CC. Where: P ad = additional power dissipation (µw); f i = input frequency (MHz); t r = input rise time (µs); 10% to 90%; t f = input fall time (µs); 10% to 90%; I CC(V) = average additional supply current (µ). I CC(V) 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.
