Hi I'm using this device in a space design. I just want to clarify the voltage requirements. In all cases, I have Vdd1 >= Vdd2, as specified. However, I'm using the device in these configurations and I want to confirm that the voltage levels are valid (it appears so from the datasheet but it's a little confusing):
Vdd1=5.0V, Vdd2=5.0V
Vdd1=3.3V, Vdd2=3.3V
Vdd1=5.0V, Vdd2=3.3V
Vdd1=5.0V, Vdd2=2.5V
Vdd1=3.3V, Vdd2=2.5V
Also, is there any requirement for the power connections for the 2 halves of the part. For instance, I have one part with Vdd1-1=5.0V, Vdd2-1=3.3V and Vdd1-2=3.3V, Vdd2-2=2.5V.
Thanks for your time,
