The LM393 IC can be regarded as equivalent to the most popular version of the LM358 operational amplifier. Although any operational amplifier can be used as a voltage comparator, the LM393 proves its advantage by providing an open collector output to make it suitable for driving loads. The output transistor can drive loads up to 50V and 50mA and is suitable for driving most TTL, MOS and RTL loads. The transistor can also isolate the load from the system ground.
