The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal to the negative supply voltage or 30V below the positive supply, whichever is less. NOTE 2: The maximum junction temperature of the 111 is 150C, while that of the 311 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 package, the derating is 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 conductor. The thermal resistance of the dual-in-line package is 100C, junction to ambient. NOTE3: These specifications apply for V, = +15V and over the operating temperature range, unless otherwise stated. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5V supply up to +15 supplies. NOTE 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 1 mA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. NOTE 5: The response time specified (see definitions) is for a 100 mV input step with S mV overdrive. NOTE 6: This specification applies for Pin 1 15V, Pin 7 +20V. 5-34LM111, LM311 INTERSIL TYPICAL PERFORMANCE INPUT OFFSET INPUT BIAS CURRENT 111 CURRENT 111 5 OFFSET ERROR 111 400 30 = 100 _ Vg = t1BV z Vs= t16V w Ta= < b 5 5 300 Z 2 > wi g ~ 10 MAXIMUM oc 2 w > 200 & 2 oO 5 5 w 2 B io RAISE 2 ra) % 2 1 5 100 i NORMAL 2 a 2 e Zz s 2 z ui Vos= Vos + 0 0 = 01 55-35-15 5 25 45 65 85 105 125 -85 -35-15 5 25 45 65 85 105 125 Z 10k 100k 1M 10M TEMPERATURE (C) TEMPERATURE (C) g INPUT RESISTANCE (2) INPUT BIAS CURRENT 311 INPUT OFFSET CURRENT 311 5 OFFSET ERROR 311 500 20 E 100 ~ Vg = 215V Zz Vg= 415 3 $ RAISED = Ss = 400 T e 5 5 RAISED 3 ws i = 2 MAXIMUM 300 5 2 2 5 P 10 & 10 2 200 4 2 a o NORMAL 5 TYPICAL a 5 NORMAL z & 100 5 rE = a z Zz wy Vos* Vos + 0 0 <1 0 10 20 30 40 50 60 70 80 0 10 20 30 40 5 60 70 80 5 10k 100k 1M 10M TEMPERATURE (C) TEMPERATURE (C) a INPUT RESISTANCE (2) INPUT CHARACTERISTICS COMMON MODE LIMITS TRANSFER FUNCTION 225 60 _ Vs = 215V _ Vs = 30 q 70 Ta= 28C 2 ~ 50 bT, > 25 OUTPUT = w > Ru * tk = 175 2 t e vit = 40V & 150 = 40 o 4 a = S126 w 6 3 8 2 30 4 100 s 2 R = 2 > R o 20 5 78 g Ee OUTPUT = R, * a 50 z 3 io [Re 6002 = eo 5 0 0 -16 -12-8 -4 0 4 8 12 16 -55 -35-15 5 25 45 65 85 105 125 ) -5 0 5 1 DIFFERENTIAL INPUT VOLTAGE (V} TEMPERATURE (C) DIFFERENTIAL INPUT VOLTAGE (mV) RESPONSE TIME FOR VARIOUS RESPONSE TIME FOR VARIOUS OUTPUT SATURATION INPUT OVERDRIVES INPUT OVERORIVES VOLTAGE 5 5 2 s Ta 28C eo 26 w w (4 ag w z 9 ee 2 rad 3 245 e ae 3 2 95 2 > 5 > > 1 2 > 0 > Q > > Ee = 100 = Sw ew 3 g 2 so 2@ ers 5 =e 2F Ta= 28C a a O a re} } > > 0 02 04 O86 O08 0 oO2 O04 O68 08 0 0 20 3 4 50 TIME (us) TIME (us) OUTPUT CURRENT (mA) 5-35LM111, LM311 TYPICAL PERFORMANCE (Cont) RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES OUTPUT LIMITING CHARACTERISTICS 140 15 mv. v z Ta + 25C = S 120 POWER 2 -2 1 aa = DISSIPATION g zo 8 22 Z 100 m eat 0 Ee ira a5 aa Zz g 9 og -5 2 3 & > -10 = 60 > = 2 4 715 > 2 3 2 0 . = 5 4 SHORT 2 so ei CIRCUIT z -' a - z 3 50 Zz 2 5 20 CURRENT ~ = @ -100 5 = 3 g 8 > 0 1 2 3 4 0 1 2 3 4 0 5 10 15 TIME (us) TIME (us) OUTPUT VOLTAGE (V!

INPUT OFFSET CURRENT: The difference between the two input currents for which the output will be driven higher than or tower than specified voltages. INPUT BIAS CURRENT: The average of the two input currents. . INPUT VOLTAGE RANGE: The range of voltage on the input terminals (common mode) over which the offset specifications apply. TEMPERATURE ('C) , TEMPERATURE ( C) VOLTAGE GAIN: The ratio of the change in output voltage to the change in voltage between the input terminals producing tt. RESPONSE TIME: The interval between the application of an input step. function and the time when the output crosses the logic threshold voltage. The input step drives the comparator from some initial, saturated input voltage to an input level just barely in excess of that required to bring the output from saturation to the logic threshold voltage. This excess is referred to as the voltage overdrive. SATURATION VOLTAGE: The low output voltage level with the input drive equal to or greater than a specified value. STROBE ON CURRENT: The current that must be drawn out of the strobe terminal to. disable the comparator. OUTPUT LEAKAGE CURRENT: The current into the output terminal with a specified output voltage relative to the ground pin and the input drive equal to or greater than a given value. SUPPLY CURRENT: The current required from the posi- tive or negative supply to operate the comparator with no output load. The power will vary with input voltage, but is specified as a maximum for the entire range of input voltage conditions. 5-36LM111,LM311 INTERSIL TYPICAL APPLICATIONS HIGH LEVEL TTL COMPATIBLE MOS LOGIC COMPATIBLE TTL COMPATIBLE OUTPUT SWING OUTPUT SWING OUTPUT SWING +16V Vuur 10V USING CLAMP DIODES TO OBTAINING +15 VOLT OUTPUT SWING ORIVING GROUND-REFERRED LOAD IMPROVE RESPONSE +15V FROM 2 LADDER INVERTING | P* .
