FEATURES
DESCRIPTION
• Applications:
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.
– Wave and pulse shapers
– Astable multivibrators
– Monostable multivibrators.
• Complies 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.
• ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
• Specified from −40 to +85 °C and −40 to +125 °C.

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.

APPLICATION INFORMATION
The slow input rise and fall times cause additional power
dissipation. This can be calculated using the following
formula:
MNA852
400
handbook, halfpage
I
CC(AV)
(µA)
Pad = fi × (tr × ICC(AV) + tf × ICC(AV)) × VCC
.
300
Where:
Pad = additional power dissipation (µW);
fi = input frequency (MHz);
200
100
positive - going
edge
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.
