2.5 V/3.3 V ALVT 16-bit registered transceiver (3-state)
The 74ALVT16543 is a high-performance BiCMOS product designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V. The device can be used as two 8-bit transceivers or one 16-bit transceiver.
The 74ALVT16543 contains two sets of eight D-type latches, with separate control pins for each set. Using data flow from A to B as an example, when the A-to-B Enable (nEAB) input and the A-to-B Latch Enable (nLEAB) input are LOW, the A-to-B path is transparent.
A subsequent LOW-to-HIGH transition of the nLEAB signal puts the A data into the latches where it is stored and the B outputs no longer change with the A inputs. With nEAB and nOEAB both LOW, the 3-State B output buffers are active and display the data present at the outputs of the A latches.
Control of data flow from B to A is similar, but using the nEBA, nLEBA, and nOEBA inputs.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

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.
