Octal buffer/line driver; inverting; 3-state
The 74AHCT240 is an 8?-?bit inverting buffer/line driver with 3?-?state outputs. This device can be used as two 4?-?bit buffers or one 8?-?bit buffer. It features two output enables (1OE and 2OE), each controlling four of the 3?-?state outputs. A HIGH on nOE causes the outputs to assume a high?-?impedance OFF?-?state. Inputs are over voltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
