† Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and EMIT OUT grounded.
Full range for LM111 is –55°C to 125°C, for LM211 is –40°C to 85°C, for LM211Q is –40°C to 125°C, and for LM311 is 0°C to 70°C.
‡ All typical values are at TA = 25°C.
NOTES: 9. The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or down to
1 V with a pullup resistor of 7.5 kΩ to VCC+. These parameters actually define an error band and take into account the worst-case
effects of voltage gain and input impedance.
10. The strobe should not be shorted to ground; it should be current driven at –3 mA to –5 mA (see Figures 13 and 27).
