The SN74ABTE16246 is an 11-bit noninverTIng transceiver designed for asynchronous two-way communicaTIon between buses. This device has open-collector and 3-state outputs. The device 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 (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effecTIvely isolated. When OE is low, the device is active.
The B port has an equivalent 25- series output resistor to reduce ringing. Active bus-hold inputs on the B port hold unused or floating inputs at a valid logic level.
The A port provides for the precharging of the outputs via VCCBIAS, which establishes a voltage between 1.
