These devices are designed to operate from a wide range of power-supply voltages, including ±15-V supplies for operational amplifiers and 5-V supplies for logic systems. The output levels are compatible with most TTL and MOS circuits. These comparators are capable of driving lamps or relays and switching voltages up to 50 V at 50 mA. All inputs and outputs can be isolated from system ground. The outputs can drive loads referenced to ground, VCC+ or VCC−. Offset balancing and strobe capabilities are available, and the outputs can be wire-OR connected. If the strobe is low, the output is in the off state, regardless of the differential input.

I was happy to receive these as I needed them for a project. I was a bit surprised to find one of the chips had solder on the pins, what the heck! I threw that one away and proceeded to work on my project. The circuit did not respond correctly, replaced with a new chip from the package, still did not respond as expected. Replaced with another one from the package, which worked as expected. I found that about less than half of the chips worked correctly. I just you get what you pay for!!
