The 'AC16245 are 16-bit bus transceivers organized as dual-octal noninverting 3-state transceivers designed for asynchronous two-way communication between data buses. The control function implementation minimizes external timing requirements These devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction control (DIR) input. The output-enable input (OE\) can be used to disable the devices so that the buses are effectively isolated. The 74AC16245 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 54AC16245 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74AC16245 is characterized for operation from -40°C to 85°C.
