1 / 7 page SN74F543 OCTAL REGISTERED TRANSCEIVER WITH 3-STATE OUTPUTS SDFS025B – D2942, MARCH 1987 – REVISED OCTOBER 1993 Copyright © 1993, Texas Instruments Incorporated 2–1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 • 3-State True Outputs • Back-to-Back Registers for Storage • Package Options Include Plastic Small-Outline and Shrink Small-Outline Packages and Standard Plastic 300-mil DIPs description 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.
