TS5A21366: voltage check
Part Number: TS5A21366
Can IN1/2 = 3.3V when use 1.8V at Vcc?
Based on spec, the maximum input voltage is Vcc. It seems like this violate spec.
The IN1 and IN2 pins are digital control inputs. Both the recommended operating conditions and absolute maximum ratings allow voltages higher than VCC.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Yes, you can have IN1/IN2 be at 3.3V when your supply is 1.8V - it will register as a logic high still as well. As Clemens mentioned, this part's rec. operating conditions allow up to 5.5V on the digital control pin when you have a VCC of 1.65V - 5.5V. The part will not sustain damage until 6.5V as mentioned in the absolute maximum operating conditions section of the datasheet.
