Description
General part information
SN74F543 Series
The SN74F543 octal transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate latch-enable (or) and output enable (or) 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 () input must be low in order to enter data from A or to output data from B. Havinglow andlow makes the A-to-B latches transparent; a subsequent low-to-high transition ofputs the A latches in the storage mode. Withandboth 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,, andinputs.
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.
