74LVC3G14
Triple inverting Schmitt trigger with 5 V tolerant input
Rev. 12 — 9 April 2013
Product data sheet
1. General description
The 74LVC3G14 provides three inverting buffers with Schmitt trigger input. It is capable of
transforming slowly changing input signals into sharply defined, jitter-free output signals.
The inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of
this device in a mixed 3.3 V and 5 V environment. Schmitt trigger action at the inputs
makes the circuit tolerant of slower input rise and fall time. This device is fully specified for
partial power-down applications using I
OFF
. The I
OFF
circuitry disables the output,
preventing the damaging backflow current through the device when it is powered down.
2. Features and benefits
Wide supply voltage range from 1.65 V to 5.5 V
5 V tolerant input/output for interfacing with 5 V logic
High noise immunity
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
24
mA output drive (V
CC
= 3.0 V)
CMOS low power consumption
Latch-up performance exceeds 250 mA
Direct interface with TTL levels
Unlimited rise and fall times
Multiple package options
Specified from
40 C
to +85
C
and
40 C
to +125
C.
3. Applications
Wave and pulse shaper for highly noisy environment
Astable multivibrator
Monostable multivibrator.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
When V
CC
= 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
For TSSOP8 package: above 55
C
the value of P
tot
derates linearly with 2.5 mW/K.
For VSSOP8 package: above 110
