Question

I see that some of the other modems have a current switching capacity on the open collector output of 300mA, is this the same for the TRB140 as it is not stated in the manual

Thank you

Hello,

Electrical characteristics of TRB140 I/O pins:

• Open collector output, max output 30 V, 300 mA;
• Digital input, 0-6 V detected as logic low and 8-30 V – logic high.
