• External hysteresis can be used while the output filter is used for internal functions.
• The plus and minus inputs of the comparator are both driven from 4-to-1
• Two software-selectable performance levels:
multiplexers, providing additional flexibility in assigning I/O as comparator inputs
during PCB design.
