SN74ABT861DW

The 'ABT861 are 10-bit transceivers designed for asynchronous communication between data buses. The control-function implementation allows for maximum flexibility in timing. These devices allow noninverted data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic levels at the output-enable (OEAB\ and 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 SN54ABT861 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT861 is characterized for operation from -40°C to 85°C.
