74AC16543 Datasheet | Texas Instruments

description 2A2 16 2A3 17 41 2B2 40 2B3 The ’AC16543 are 16-bit registered transceivers that contain two sets of D-type latches for temporary storage of data flowing in either direction. 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 GND 2A4 2A5 2A6 VCC 2A7 2A8 18 19 20 21 22 23 24 39 GND 38 2B4 37 2B5 36 2B6 35 VCC 34 2B7 33 2B8 register to permit independent control in either GND 25 32 GND direction of data flow. 2CEAB 26 31 2CEBA The A-to-B enable (CEAB) input must be low to enter data from A or to output data to B. Having 2LEAB 27 2OEAB 28 30 2LEBA 29 2OEBA 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 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 is characterized for operation over the full military temperature range of - 55°C to 125°C. The 74AC16543 is characterized for operation from - 40°C to 85°C.
