This 32-bit noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVC32245 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. …
