74LVT16543A

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
