3.3 V Octal transceiver with direction pin; inverting; 3-state
The 74LVT640 is an 8?-?bit inverting transceiver with 3?-?state outputs. The device features an output enable (OE) and send?/?receive (DIR) for direction control. A HIGH on OE 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.
