The supply voltage range is 2.25 V to 3.63 V, so a 3.3 V rail is within spec. The CMOS output swings rail-to-rail at that voltage."},{"question":"What is the closest pin-compatible alternative to the DSC1221BL2-25M00000?","answer":"Within the DSC12X1 series, other frequency variants share the same 6-VDFN package and pinout.
