The 'ABT16863 are 18-bit noninverting transceivers designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements.
The 'ABT16863 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.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT16863 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT16863 is characterized for operation from -40°C to 85°C.
