ISO1228: OUTx Io current

cory chase

Part Number: ISO1228

Tool/software:

Hello All,

What is the nominal value of the Outx pin current? I see in the absolute ratings Io is +/- 15mA. But I don't see any recommended current levels for the output pins in parallel mode. Just curious if I can drive LED's on the logic side with the Outx pins.

The test condition for V_OH and V_OL is 1 mA, but this is the worst case for a 1.8 V supply. For higher supplies, nothing is specified in the current revision of the datasheet, but a few mA should be possible.

Hi Cory,

Thank you for reaching out.
The recommended output current values for ISO1228 are currently not listed. Please consider the below table as reference for the recommend output current of logic output channels. Thanks.

Regards,
