They can be used as two 8-bit transceivers or one 16-bit transceiver. 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. 1 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 11 46 12 45 13 44 14 43 15 42 16 41 17 40 18 39 19 38 20 37 21 36 22 35 23 34 24 33 25 32 26 31 27 30 1OEBA 1LEBA 1CEBA GND 1B1 1B2 VCC 1B3 1B4 1B5 GND 1B6 1B7 1B8 2B1 2B2 2B3 GND 2B4 2B5 2B6 VCC 2B7 2B8 GND 2CEBA 2LEBA 2OEBA The A-to-B enable (CEAB) input must be low to 28 29 enter data from A or to output data to B. Having CEAB low and LEAB low makes the A-to-B latches transparent; a subsequent low-to-high transition at LEAB puts the A latches in the storage mode. Data flow from B to A is similar, but requires using the CEBA, LEBA, and OEBA inputs. The 74AC16543 74AC16543 is packaged in TI's shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area. The 54AC16543 54AC16543 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74AC16543 74AC16543 is characterized for operation from -40°C to 85°C.
