descriptionThe ’ABT16640 are inverting 16-bit transceivers
designed for asynchronous communication
between data buses.
These devices can be used as two 8-bit
transceivers or one 16-bit transceiver. It allows
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 direction-control (1DIR and 2DIR)
inputs. The output-enable (1OE and 2OE) inputs
can be used to disable the device so that the
buses are effectively isolated.
To ensure the high-impedance state during power up or power down, 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 SN54ABT16640 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT16640 is characterized for operation from –40°C to 85°C.
