74LVT16543ADL

3.3 V 16-bit registered transceiver; 3-state

The 74LVT16543A is a 16-bit registered transceiver with 3-state outputs. The device can be used as two 8-bit transceivers or one 16-bit transceiver.

Data flow in each direction is controlled by intput enable (nEAB and nEBA), latch enable (nLEAB and nLEBA), and output enable (nOEAB and nOEBA) inputs. For A to B data flow, the device operates in the transparent mode when (nEAB) and (nLEAB) are LOW. A subsequent LOW-to-HIGH transition of the nLEAB input latches the data and the outputs no longer change with the inputs. A HIGH on either nEAB or nOEAB causes the outputs to assume a high-impedance OFF-state.

Control of data flow from B to A is similar, but using the nEBA, nLEBA, and nOEBA inputs. 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.
