FEATURES
•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, Tamb = 25°C.
•Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb = 25°C.
•Output capability: standard
•ICC category: SSI
APPLICATIONS
•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.
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.

NOTES:
1.CPD is used to determine the dynamic power dissipation (PD in mW) 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 ªrecommended operating conditionsº 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.
