Hex inverting Schmitt-trigger with
5 V tolerant input
Product specification
74LVC14A
FEATURES
• Wide supply voltage range from 1.2 to 3.6 V
• CMOS low power consumption
• Direct interface with TTL levels
• Inputs accept voltages up to 5.5 V
• Complies with JEDEC standard no. 8-1A
• 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 74LVC14A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 or 5 V devices. This
feature allows the use of these devices as translators in a
mixed 3.3 and 5 V environment.
The 74LVC14A provides six inverting buffers with
Schmitt-trigger action. It is capable of transforming slowly
changing input signals into sharply defined, jitter-free
output signals.
APPLICATIONS
• Wave and pulse shapers for highly noisy environments
• Astable multivibrators
• Monostable multivibrators.

CONDITIONS
CL = 50 pF; VCC = 3.3 V
VCC = 3.3 V; notes 1 and 2
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. The condition is VI = GND to VCC.
