XTR111: DIGITAL OUTPUT (EF) max current

Tomasz Jastrzebski

Part Number: XTR111

Tool/software:

Hi TI, what is the max digital (EF) output current? Specs do not seem to say. In particular I would like to know if EF pin can be used to drive 5 mA LED attached to VDD.

When the current is more than 2.2 mA, V_OL is no longer guaranteed. At 5 mA, V_OL might be much more than 2 V.

Thank you Clemens, I understand it is just really not designed for that but 2 mA may be sufficient.

Tomasz, correct - XTR111 was not designed for 5mA IEF current.

Thank you Clemens.
