74LV14A
Hex inverting Schmitt trigger
Rev. 3 — 2 November 2016
Product data sheet
1. General description
The 74LV14A is a hex inverter with Schmitt-trigger inputs, capable of transforming slowly
changing input signals into sharply defined, jitter-free output signals.
Inputs are overvoltage tolerant. This feature allows the use of these devices as translators
in mixed voltage environments.
This device is fully specified for partial power down applications using IOFF. The IOFF
circuitry disables the output, preventing the potentially damaging backflow current through
the device when it is powered down.
2. Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Maximum tpd of 10 ns at 5 V
Typical VOL(p) < 0.8 V at VCC = 3.3 V, Tamb = 25 C
Typical VOH(v) > 2.3 V at VCC = 3.3 V, Tamb = 25 C
Supports mixed-mode voltage operation on all ports
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 250 mA per JESD 78 Class II
ESD protection:
HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 3 kV
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 2 kV
Specified from 40 C to +85 C and from 40 C to +125 C

If the input current ratings are observed, the minimum input voltage ratings may be exceeded.
[2]
If the output current ratings are observed, the output voltage ratings may be exceeded.
[3]
This value is limited to 7 V maximum.
[4]
For TSSOP14 packages: above 75 C, the value of Ptot derates linearly at 7 mW/K.

CPD is used to determine the dynamic power dissipation PD (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 Volts.
