DESCRIPTION

The 74LV368 a low–voltage Si–gate CMOS device and is pin and function compatible with 74HC/HCT368.

The 74LV368 is a hex inverting buffer/line driver with 3–state outputs. The 3–state outputs (nY) are controlled by the output enable inputs 1OE assume a high impedance OFF–state.

and 2OE. A HIGH on nOE causes the outputs to

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.
