description

The 'AC16640 are inverting 16-bit transceivers designed forasynchronous communication between data buses.

These devices can be used as two 8-bit transceivers or one 16-bittransceiver. They allow data transmission from the A bus to the B busor from the B bus to the A bus, depending on the logic level at thedirection-control (1DIR and 2DIR) inputs. The output-enable (1 and 2) inputs can be used to disable thedevice so that the buses are effectively isolated.

The 74AC16640 is packaged in TI's shrink small-outline package,which provides twice the I/O pin count and functionality of standardsmall-outline packages in the same printed-circuit-board area.

The 54AC16640 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The 74AC16640is characterized for operation from -40°C to 85°C.
