(TOP VIEWI
The LM111, LM211, and LM311 are single high-
speed voltage comparators. These devices are EMIT OUT VCC +
designed to operate from a wide range of power IN + COL OUT
supply voltage, including ± 15-V supplies for IN — BAL/STRB
operational amplifiers and 5-V supplies for logic VCC — BALANCE
systems. The output levels are compatible with
most TTL and MOS circuits. These comparators
LM111 . . . U FLAT PACKAGE 3
are capable of driving lamps or relays and
(TOP VIEWI
switching voltages up to 50 V at 50 mA. All
inputs and outputs can be isolated from system EMIT OUT VCC +
ground. The outputs can drive loads referenced IN + COL OUT rs
to ground, Vcc + or Vcc _ . Offset balancing IN— NC o
and strobe capability are available and the NC BAL/STRB at
outputs can be wire-OR connected. If the strobe VCC- BALANCE ar
is low, the output will be in the off state p
regardless of the differential input. m

NOTES: 5. The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or
o down to 1 V with a pull-up resistor of 7.5 1(0 to Vcc + . Thus these parameters actually define an error band and take into
i account the worst-case effects of voltage gain and input impedance.
s 6. The strobe should not be shorted to ground; it should be current driven at -3 to -5 mA, e.g., see Figures 13 and 27.
