DESCRIPTION
The 74LV240 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT240.
The 74LV240 is an octal inverting buffer/line driver with 3-State
outputs. The 3-State outputs are controlled by the output enable
inputs 1OE and 2OE. A HIGH on nOE causes the outputs to
assume a high impedance OFF-state. The 74LV240 is identical to
the 74LV244 but has inverting 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 “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.
