The devices are non-inverting drivers. The outputs are configured into 2 groups of 1-in, 5-out with independent output enable. Group B has an extra MON output. Excellent output signals to power and ground ratio minimize power and ground noise, and also improves output performance. PI49FCT32805 integrate series damping resistors on all outputs.
