Octal buffer/line driver; 3-state
The 74ABT244 is an 8?-?bit buffer/line driver with 3?-?state outputs. The device can be used as two 4?-?bit buffers or one 8?-?bit buffer. The device 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. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

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.
