111 211 311 GENERAL DESCRIPTION The (M111, LM211, and LM311 are voltage comparators with about one-thousandth the input current of the LM106 and M107. These comparators are designed to operate from stan- dard +15V operational amptifier supplies to a single +5V supply used for IC logic. Their outputs are compatible with DTL, RTL, TTL, and MOS devices. Offset balancing is provided, and the outputs can be OR wired. The LM111 operates over the full military temperature range of ~55C to +125C. The LM211 is the same as the LM111 except its performance is guaranteed from 25C to +85C. The LM311 is the commercial version which operates from 0C to +70C.

This rating applies for +15V supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage timit is equal to the negative supply voltage of 30V below the positive supply, whichever is less. 2. The maximum junction temperature of the LM111 is 150C, white that of the LM311 is +85C. For operating at elevated temperatures, devices in the TO-5 package must be derated based on a thermal resistance of 150C/W, junction to ambient, or 45C/W, junction to case. For the flat pack, derate based on a thermal resistance of 185C/W when mounted on a 1/16-inch-thick epoxy glass board with ten, 0.03-inch-wide, 2 ounce copper conductors. The thermal resistance of the dual-in-line (DE) package is 100C/W, junction to ambient. 3. These specifications apply for Vg = +15V and -B5C < Ta < +1 25C, unlass otherwise stated. With the LM311, however, all temperature specifi- cations are limited to O0C < Ta < +70C. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5V supply up to +15V supplies 4. The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1mMA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. 5. The response time specified {see definitions) is for a 100mV input step with SmV overdrive.
