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 buf fer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs OE

A HIGH on OEn causes the outputs to assume a high impedance OFF–state.

CL = 15pF VCC = 3.3V

and OE2.

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.
