FEATURES
•Optimized for Low Voltage applications: 1.0 to 3.6V
•Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V
•Typical VOLP (output ground bounce) 0.8V @ VCC = 3.3V, Tamb = 25°C
•Typical VOHV (output VOH undershoot) 2V @ VCC = 3.3V, Tamb = 25°C
•Non-inverting outputs
•Output capability: bus driver
•ICC category: MSI
DESCRIPTION
The 74LV541 is a low±voltage CMOS device and is pin and function compatible with 74HC/HCT541.
The 74LV541 is an octal non-inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable
inputs OE1 and OE2.
A HIGH on OEn causes the outputs to assume a high impedance OFF±state.

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 capacity 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.
