Hi All.
I need to connect my MCU with an external SPI device which have Logic levels of HIGH 3V and LOW 2V. From the Device to MCU Logic shift I can convert the Voltage 3V/2V to 5V/0V respectively using LM339. But I am facing problem in the other direction conversion of 5V/0V to 3V/2V.
Can anyone advice any comparator Circuit or IC which I can use to make the LOW Output a Positive Voltage (i.e. 2V)? It will be great if there any Quad Differential Comparator available.
Thank you in advance.
Regards.
