FEATURES
APPLICATIONS
• Wide operating voltage: 1.0 to 5.5 V
• Optimized for Low Voltage applications: 1.0 to 3.6 V
• Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
• Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V,
• Wave and pulse shapers for highly noisy environments
DESCRIPTION
The 74LV14 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT14.
Tamb = 25°C.
The 74LV14 provides six inverting buffers with Schmitt-trigger
action. It is capable of transforming slowly changing input signals
into sharply defined, jitter-free output signals.
• Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V,
Tamb = 25°C.
• Output capability: standard
• ICC category: SSI

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD × VCC2 × fi (CL × VCC2 × fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
(CL × VCC2 × fo) = sum of the outputs.
2. The condition is VI = GND to VCC.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

APPLICATION INFORMATION
The slow input rise and fall times cause additional power dissipation,
this can be calculated using the following formula:
Pad
= fi × (tr × ICCa + tf × I CC a) × VCC.
Where:
Pad = additional power dissipation (W)
= input frequency (MHz)
fi
tr
= input rise time (ns); 10% – 90%
= input fall time (ns); 10% – 90%
tf
I CC a = average additional supply current (A)
Average I CC adiffers with positive or negative input transitions, as
shown in Figure 7.
