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: bus driver
•ICC category: MSI
DESCRIPTION
The 74LV126 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC/HCT126.
The 74LV126 consists of four non-inverting buffers/line drivers with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable input (nOE). A LOW at nOE causes the outputs to assume a high impedance OFF-state.

NOTE:
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.

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.
DC ELECTRICAL CHARACTERISTICS
Over recommended operating conditions, voltages are referenced to GND (ground = 0 V)
