The SN74F543 octal transceiver 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 outputs are  
characterized to sink 24 mA while the B outputs  
are characterized to sink 64 mA.

The A-to-B enable (CEAB) input must be low in order to enter data from A or to output data from B. Having CEAB  
low and LEAB low makes the A-to-B latches 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.  
The SN74F543 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count  
and functionality of standard small-outline packages in less than half the printed-circuit-board area.  
The SN74F543 is characterized for operation from 0°C to 70°C.
