ADG3245 can change 2.5V to 1.8V it is allow bidirectional signals,
so my question is ,
1, if signal comes from 1.8V side , to ADG3245 the output is connected to 2.5V side.
can this working good?
2, When VCC=2.5V SEL=2.5V BE=0 in this mode it makes 2.5 to 1.8 V
and Port A must connect to VCC side and Port B must connect to 1.8V side ,is this right ?
Here are the comments:
1. The ADG3245 can only do down translation (2.5V down to 1.8V). This is discussed in the Mixed Voltage Operation, Level Translation section of the ADG3245 datasheet on page 9. If signal comes from 1.8V side, the output will be limited to approximately 1.8V as well. Please see figure 8 page 9.
2. Yes, you are correct.
Let me know if this helps.
Thank you for your answer. I have to change this IC to a real Bidirectional level translator.
