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.
