具有三态输出的16位总线收发器 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS
Description
This 16-bit dual-octal noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCH16245 device is designed for asynchronous communication between two data buses. The logic levels of the direction-control DIR input and the output-enable OE input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports is always active and must have a logic high or low level applied to prevent excess ICC and ICCZ.
