Dear Sir/Ms.

When using R2 to design the voltage of Vref_A, is it as follows:

Vref_A=1.5V@VPU=3.3VDevice 1.5-5.5V

Vref_A=1.0V@VPU=3.3V Device 1.0-5.5V

There is also VTH related to the calculation of the value of R2. What is the parameter of VTH?

Best Regards,

Kami Huang

  • Hi Kami,

    .85 V should be used for VTH since its worst case.

    Check out our new AXC family of Voltage Translators!
