A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the direction control DIR input.
