Description
The LM111, LM211, LM311 are voltage comparators that have low input currents. They are also designed to operate over a wide range of supply voltages: from standard ±15V operational amplifier supplies down to the single +5V supply used for IC logic. Their output is compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +50V at output currents as high as 50mA.

2 Absolute maximum ratings & operating conditions
Table 1. Absolute maximum ratings (AMR)
- This rating applies for ±15V supplies. The positi ve input voltage limit is 30V above the negative. The
- P d is calculated with Tamb = +25°C, Tj = +150°C and Rthja = 100°C/W for the DIP8 package, and
Rthja = 175°C/W for the SO-8 package. Table 2. Operating conditions
3 Electrical characteristics
Table 3. V CC
- The offset voltage, offset current and bi as current specifications apply for any supply voltage from a single +5V supply up to
case of voltage gain and input impedance.
- The response time specified is for a 100mV input step with 5mV overdrive.

5 Package mechanical data
In order to meet environmental requirements, STMicroelectronics offers these devices in ECOPACK® packages. These packages have a Lead-free second level interconnect. The category of second level interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an STMicroelectronics trademark. ECOPACK specifications are available at: www.st.com
