SN74ABTE16246 具有三态输出和集电极开路输出的 11 位入射波开关总线收发器
SN74ABTE16246 描述
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
