10-BIT TRANSCEIVERS WITH 3-STATE OUTPUTS

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 55C to 125C. The SN74ABT861 is characterized for operation from 40C to 85C By Texas Instruments
