See Input (R) Protection discussion in the LT 1011 data sheet. Note 2: TJMAX = 150C. Note 3: Output is sinking 1.5mA with VOUT = 0V. Note 4: These specifications apply for all supply voltages from a single 5V to 15V, the entire input voltage range and for both high and low output states. The high state is ISINK = 100A, VOUT = (V+ - 1V) and the low state is ISINK = 8mA, VOUT = 0.8V. Therefore, this specication defines a worst-case error band that includes effects due to common mode signals, voltage gain and output load. Note 5: Drift is calculated by dividing the offset difference measured at minimum and maximum temperatures by the temperature difference. Note 6: Response time is measured with a 100mV step and 5mV overdrive. The output load is a 500 resistor tied to 5V. Time measurement is taken when the output crosses 1.4V. -14.5 0.5 6 (Typ) 2.5 500 6 (Typ) 2.5 500 6 (Typ) 500 6 (Typ) A pF Note 7: Do not short the STROBE pin to ground. It should be current driven at 3mA to 5mA for the shortest strobe time. Currents as low as 500A will strobe the RH1011 if speed is not important. External leakage on the STROBE pin in excess of 0.2A when the strobe is "off" can cause offset voltage shifts. Note 8: See graph, Input Offset Voltage vs Common Mode Voltage on the LT1011 data sheet. Note 9: Guaranteed by design, characterization or correlation to other tested parameters. Note 10: VS = 15V, VCM = 0V, RS = 0, TA = 25C, VGND = V-, output at Pin 7, unless otherwise noted. Note 11: VGND = 0V. Rev.

INPUT+ (PIN 2): Non-Inverting Input of Comparator INPUT- (PIN 3): Inverting Input of Comparator V- (PIN 4): Negative Supply Voltage OUT (PIN 7): Open-Collector Output of Comparator BALANCE (PIN 5): Balance Input. This input can be used to adjust the input voltage offset or to add hysteresis. If offset balancing or hysteresis is not used, the BALANCE pins should be connected together with a 0.1F capacitor. BALANCE/STROBE (PIN 6): Strobe Input Pin. Using this pin, the output transistor can be forced to an "off" state, giving a "hi" output at the collector (Pin 7). This input can be used to adjust the input voltage offset or used to add hysteresis. If offset balancing or hysteresis is not used, the BALANCE pins should be connected together with a 0.1F capacitor. V+ (PIN 8): Positive Supply Voltage Rev.
