Question:
Can MAX3097E / MAX3098E Alarm Pins be used as a driver for another circuit such as an LED driver?
Answer:
The ALARM_ outputs are push-pull CMOS outputs, but the VOH and VOL are not specified in the electrical characteristics table. The receiver outputs, OUT_, are push-pull CMOS outputs, and specified for VOH and VOL under various supply and load conditions in the electrical characteristics table. The ALARM_ outputs share the same basic output driver design as the OUT_ outputs, but are not specified and guaranteed in the electrical characteristics table. There is no specification on how much current the ALARM_ pins can sink or source, but their drive characteristics should be same as those shown for the "Receiver Output Low (High) Voltage vs. Output Current" in the typical operating characteristics on datasheet page 4.
