74LVC1G14
Single Schmitt-trigger inverter
Rev. 14 — 2 December 2016
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 IOFF. The IOFF
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 (VCC = 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.
Specified from 40 C to +85 C and 40 C to +125 C.

[1]
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2]
When VCC = 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
[3]
For TSSOP5 and SC-74A packages: above 87.5 C the value of Ptot derates linearly with 4.0 mW/K.
For XSON6 and X2SON5 package: above 118 C the value of Ptot derates linearly with 7.8 mW/K.

CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi + (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.
