description
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 V_CC 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 V_CC 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.
