It allowsdata transmission from the A bus to the B bus orfrom the B bus to the A bus, depending on the logiclevel at the direction-control (1DIR and 2DIR)inputs. The output-enable (1OE and 2OE) inputscan be used to disable the device so that thebuses are effectively isolated.1DIR1B11B2GND1B31B4VCC1B51B6GND1B71B82B12B2GND2B32B4VCC2B52B6GND2B72B82DIR1234567891011121314151617181920212223244847464544434241403938373635343332313029282726251OE1A11A2GND1A31A4VCC1A51A6GND1A71A82A12A2GND2A32A4VCC2A52A6GND2A72A82OETo ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullupresistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.The SN54ABT16640 is characterized for operation over the full military temperature range of –55°C to 125°C.The SN74ABT16640 is characterized for operation from –40°C to 85°C.FUNCTION TABLE(each 8-bit section)INPUTSOELLHDIRLHXOPERATIONB data to A busA data to B busIsolationPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.Widebus and EPIC-ΙΙB are trademarks of Texas Instruments Incorporated.PRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.
