SN6505A: Can SN6505A EN pin be driven with MCU GPIO?

Hi Manuel,

Yes it does - there was some confusion on both our parts (mine and the customer's) because in the datasheet it states 0.7Vcc is the max voltage that will allow the enable pin to turn on (page 6). So I read it as the enable pin will be enabled between 0.3Vcc to 0.7Vcc.

For my learning, and for future reference for others, could you provide a little more clarification on what that means? If enable pin isn't enabled until voltage is 0.7Vcc, what happens right above 0.3Vcc, and below 0.3Vcc?

Thank you,
Lauren

Lauren,

When the Enable voltage level is below 0.3xVcc, the SN6505 is guaranteed to be disabled. Between 0.3xVcc and 0.7xVcc, the enable thresholds vary from device to device. Only the minimum and maximum values are specified for clarity and usefulness.

Are there additional questions I can help answer?


Thank you for your time,
Manuel Chavez

Hi Manuel,

No, thank you, that answers my question.

Thank you very much for your assistance!

Thanks,

Lauren
