Separate Latch Enable and Output Enable inputs are provided for each register to permit independent con- trol of inputting and outputting in either direction of data flow. The A outputs are guaranteed to sink 24 mA while the B outputs are rated for 64 mA. Features ■8-bit octal transceiver ■Back-to-back registers for storage ■Separate controls for data flow in each direction ■A outputs sink 24 mA ■B outputs sink 64 mA Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

www.fairchildsemi.com 2 7 4 F 5 4 3 Unit Loading/Fan Out Functional Description The F543 contains two sets of eight D-type latches, with separate input and output controls for each set. For data flow from A to B, for example, the A-to-B Enable (CEAB) input must be LOW in order to enter data from A0–A7 or take data from B0–B7, as indicated in the Data I/O Control Table. With CEAB LOW, a LOW signal on the A-to-B Latch Enable (LEAB) input makes the A-to-B latches transparent; a subsequent LOW-to-HIGH transition of the LEAB signal puts the A latches in the storage mode and their outputs no longer change with the A inputs. With CEAB and OEAB both LOW, the 3-STATE B output buffers are active and reflect the data present at the output of the A latches. Con- trol of data flow from B to A is similar, but using the CEBA, LEBA and OEBA inputs. Data I/O Control Table H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial A-to-B data flow shown; B-to-A flow control is the same, except using CEBA, LEBA and OEBA Logic Diagram Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.
