description /ordering information 2BI 20 GND 21 29 3BI 28 GND The SN74ABTE16246 is an 11-bit noninverting transceiver designed for asynchronous two-way munication between buses. This device has 2BO 22 1BO 23 1BI 24 27 2A 26 1A 25 OE 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-Ω 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 1.3 V and 1.7 V when VCC is not connected. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not remended.
