Supply range and output flexibility
The LM311DR: Its output stage can be configured as MOS, open-collector, open-emitter, or TTL, letting it interface directly with downstream logic families or drive loads up to 50 mA without a buffer transistor.
Input offset and bias — signal-chain fit
Quiescent current maxes at 7.5 mA, making it suitable for always-on comparator banks in multi-channel monitoring boards where per-channel power budget is under 10 mA.
RoHS3 compliant, with no REACH or UL certification cited in the available documentation; the base product number is LM311, and the DR suffix denotes the 8-SOIC tape-and-reel variant.
