74LVC1G14
Single Schmitt-trigger inverter
Rev. 12 — 6 August 2012
Product data sheet
1. General description
The 74LVC1G14 provides the inverting buffer function with Schmitt-trigger input. It is
capable of transforming slowly changing input signals into sharply defined, jitter-free
output signals.
The input 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 input
makes the circuit tolerant for 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
High noise immunity
Complies with JEDEC standard:
JESD8-7 (1.65 V to 1.95 V)
JESD8-5 (2.3 V to 2.7 V)
JESD8-B/JESD36 (2.7 V to 3.6 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
Input accepts voltages up to 5 V
Multiple package options
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V.

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 TSSOP5 and SC-74A packages: above 87.5
C
the value of P
tot
derates linearly with 4.0 mW/K.
For XSON6 and X2SON5 package: above 118
C
the value of P
