74LVT16543A Overview
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.
