DESCRIPTION
The 74LV14 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT14. 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.
CONDITIONS CL = 15 pF; VCC = 3.3 V See Notes 1 and 2

NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W) PD = CPD x VCC2 x fi ) (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL x VCC2 x 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 x (tr x ICCa + tf x I CC a) x VCC.
Where: Pad = additional power dissipation (mW) = 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 (mA) Average I CC adiffers with positive or negative input transitions, as shown in Figure 7.
