SN74ABTE16246DL

具有三态11位入射波交换总线收发器和集电极开路输出 11-BIT INCIDENT-WAVE SWITCHING BUS TRANSCEIVER 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.
