Hi support team.

Is VCC range for 3.3V correct in datasheet P11 "Recommended Operating Conditions"?

Is this typo?

Higa-san,

This is a typo, it should say:

Minimum - 3.0V, Typical - 3.3V, Maximum - 3.6V.

We will update the datasheet accordingly, thanks for pointing this out.

Hi Eric-san

Thank you for your quick reply.

I understood.

There is one more question, I would like to ask you regarding this device and TL16C554A.

If RTS*, CTS*,DTR*,DSR*,DCD*,RI* pin aren't used, can these pins left open?

If not, what should I do?

what about RTS*, CTS*,DTR*,DSR*,DCD*,RI* of tL16C554A?

Best regards,

Higa

Higa-san,

It seems like if you're not using those pins then you're not using the handshaking and data validation features of this device. If that's the case, then those pins can be left floating.
