The control-function implementation minimizes external timing requirements. The ’ACT16863 can be used as two 9-bit transceivers or one 18-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the output-enable (OEAB or OEBA) 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.
