Description
General part information
SN74LVC543A Series
This octal registered transceiver is designed for 1.65-V to 3.6-V VCCoperation.
The SN74LVC543A contains two sets of D-type latches for temporary storage of data flowing in either direction. 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\ places 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 for B to A is similar to that of A to B, but uses CEBA\, LEBA\, and OEBA\.
