SN74LVCHR32245A 具有三态输出的 32 位总线收发器
This 32-bit (quad-octal) noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCHR32245A is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements.
This device can be used as four 8-bit transceivers, two 16-bit transceivers, or one 32-bit transceiver. It 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.
The data I/Os and control inputs are overvoltage tolerant. This feature allows the use of this device for down translation in a mixed-voltage environment
