Description
General part information
SN74LVCH16543A Series
This 16-bit registered transceiver is designed for 1.65-V to 3.6-V VCCoperation.
The SN74LVCH16543A can be used as two 8-bit transceivers or one 16-bit transceiver. Separate latch-enable (LEAB\ or LEBA\) and output-enable (OEAB\ or OEBA\) inputs are provided for each register, to permit independent control in either direction of data flow.
The A-to-B enable (CEAB\) input must be low to enter data from A or to output data from B. If CEAB\ is low and LEAB is low, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB\ puts the A latches in the storage mode. With CEAB\ and OEAB\ both low, the 3-state B outputs are active and reflect the data present at the output of the A latches. Data flow from B to A is similar, but requires using the CEBA\, LEBA\, and OEBA\ inputs.
