ISO3080: Isolation of DC level as opposed to higher data rate

Part Number: ISO3080

Hi,

Can someone confirm whether the ISO3080 can transmit a DC level?

The datasheet describes its ability to transmit up to 20mbps, but nowhere can I find details on minimum frequency.

It occurs to me that as it is a 'capacitive' coupling device, there would be a minimum frequency for the data and as such transmitting a simple logic state (nominally DC), it would not be able to do.

Please can someone tell me if it can, and if not, what devices TI do that can transmit a DC level?

many thanks
