1. General description
The 74LVC14A is a high-performance, low-power, low-voltage, Si-gate CMOS device and
superior to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this
device as a translator in a mixed 3.3 V 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.
2. Features
Wide supply voltage range from 1.2 V to 3.6 V
5 V tolerant input for interfacing with 5 V logic
CMOS low-power consumption
Direct interface with TTL levels
Inputs accept voltages up to 5.5 V
Unlimited input rise and fall times
Complies with JEDEC standard:
JESD8-B/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM EIA/JESD22-A114-B exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V
Multiple package options
Specified from 40 °C to +85 °C and from 40 °C to +125 °C
3. Applications
Wave and pulse shapers for highly noisy environments
Astable multivibrators
Monostable multivibrators

4. Quick reference data
[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 V;
N = number of inputs switching;
Σ(CL× VCC2× fo) = sum of the outputs.
[2] The condition is VI = GND to VCC.

20. Definitions
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
