The 2B5 21 36 2A5 control-function implementation minimizes VCC 22 35 VCC external timing requirements. 2B6 23 34 2A6 2B7 24 33 2A7 The ’ACT16863 can be used as two 9-bit GND 25 32 GND transceivers or one 18-bit transceiver. They allow data transmission from the A bus to the B bus or 2B8 26 31 2A8 from the B bus to the A bus, depending on the logic 2B9 27 30 2A9 level at the output-enable (OEAB or OEBA) 2OEAB 28 29 2OEBA inputs. The 74ACT16863 is packaged in TI’s shrink small-outline package (DL), which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area. The 54ACT16863 is characterized for operation over the full military temperature range of –55°C to 125°C. The 74ACT16863 is characterized for operation from –40°C to 85°C.
