Hex inverting Schmitt trigger 74HC14; 74HCT14
FEATURES
• Applications:
– Wave and pulse shapers
– Astable multivibrators
– Monostable multivibrators.
• Complies with JEDEC standard no. 7A
• ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
DESCRIPTION
The74HC14and74HCT14arehigh-speedSi-gateCMOS
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.
MM EIA/JESD22-A115-A exceeds 200 V.
• Specified from −40 to +85 °C and −40 to +125 °C.

APPLICATION INFORMATION
The slow input rise and fall times cause additional power
dissipation. This can be calculated using the following
formula:
Pad=fi×(tr× I
CC(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%;
I
= average additional supply current (µA).
CC(AV)
I
differs with positive or negative input transitions, as
CC(AV)
shown in Figs 16 and 17.
For 74HC/HCT14 used in a relaxation oscillator circuit,
see Fig.18.
Note to application information
All values given are typical unless otherwise specified.
