Overview
The LM211DT is a voltage comparator produced by STMicroelectronics. It is part of the LM111, LM211, and LM311 family of voltage comparators, known for their low input currents and wide range of supply voltage compatibility. These comparators can operate from standard ±15V operational amplifier supplies down to a single +5V supply used in IC logic. The output of the LM211DT is compatible with RTL-DTL, TTL, and MOS circuits, and it can switch voltages up to +50V at output currents as high as 50mA.
