Product data sheet
1. General description
The 74F543 octal latched transceiver contains two sets of D-type latches for temporary
storage of data flowing in either direction. Separate latch enable (LEAB, LEBA) and output
enable (OEAB, OEBA) inputs are provided for each register to permit independent control
of data transfer in either direction. The A outputs are guaranteed to sink 24 mA while the B
outputs are rated for 64 mA.

6.2 Description
The 74F543 contains two sets of eight D-type latches, with separate control pins for each
set.
Using data flow from A-to-B as an example, when the A-to-B enable (EAB) input, the
A-to-B latch enable (LEAB) input and the A-to-B output latch enable (OEAB) are all LOW,
the A-to-B path is transparent.
A subsequent LOW-to-HIGH transition of the LEAB signal puts the A data into the latches
where it is stored and the B outputs no longer change with the A inputs. With EAB and
OEAB both LOW, the 3-state B output buffers are active and display the data present at
the outputs of the A latches.
Control of data flow from B-to-A is similar, but using the EBA, LEBA, and OEBA inputs.
