11-bit Incident-wave Switching Bus Transceivers With 3-state And Open-collector Outputs

  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 1.3 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 recommended. 23 24 26 25 1BO 1BI 1A OE
