ADG1419 and ADG1421 switch

I am using ADG1419 analog switch (SPDT) in opamp circuit. The IN pin of switch is driven from microcontroller. After making IN=1, I observed controller pin voltage dropped to 2.4V. When I checked input current of IN pin it was 35 mA. Same switch if driven external supply input, IN pin current is 35 mA. Does this IC have any issue?

Later I changed circuit and used ADG1421 (Dual SPST switch), for this switch IN pin current is 3 mA. This is also more than expected.
