The PI49FCT3805 is a non-inverting driver, whereas the PI49FCT3806 is an inverting driver. 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.
