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
MM EIA/JESD22-A115-A 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. 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.

APPLICATION INFORMATION
The slow input rise and fall times cause additional power
dissipation. 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.
