74ALVCH16543

16-bit D-type registered transceiver; 3-state

TThe 74ALVCH16543 is a 16-bit registered transceiver with bus hold inputs and 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 transparen 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. 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.
