3.3 V octal buffer/line driver; 3-state
The 74LVT244B; 74LVTH244B 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. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs.

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.
