All these comparators were designed specifically to operate from a single power supply aver a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC + -1.5V, but either or both inputs can go to +30V without damage The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained Posistive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V bellow the negative power supply, if used). 3/10 LM139,A-LM239,A-LM339,A SUPPLY CURRENT versus SUPPLY VOLTAGE INPUT CURRENT versus SUPPLY VOLTAGE 1 SUPPLY CURRENT (mA) 80 INPUT CURRENT (nA) Tamb = -55°C Tamb = 0°C Tamb= +25°C Tamb = +70°C 0.8 0.6 0.4 60 40 20 Vi = 0V R = 10 9 Ω i Tamb = -55°C Tamb = 0°C Tamb= +25°C Tamb = +125°C 0.2 R= Tamb = +125°C Tamb = +70°C 0 10 20 30 SUPPLY VOLTAGE (V) 40 0 10 20 30 SUPPLY VOLTAGE (V) 40 OUTPUT SATURATION VOLTAGE versus OUTPUT CURRENT RESPONSE TIME FOR VAROIOUS INPUT OVERDRIVES - NEGATIVE TRANSITION SATURATION VOLTAGE (V) OUTPUT VOLTAGE (V) 10 10 10 10 10 1 Out of saturation 0 Tamb = +125°C -1 Tamb = -55°C -2 Tamb= +25°C -3 -2 -1 0 1 2 6 5 4 3 2 1 0 0 -50 -100 INPUT VOLTAGE (mV) Input overdrive : 5mV 20mV eI 5V 5.1kΩ eo 100mV Tamb= +25°C 0 0.5 1 1.5 TIME (µs) 2 10 10 10 10 10 OUTPUT SINK CURRENT (mA) RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - POSITIVE TRANSITION 6 15 4 3 2 1 0 00 50 0 OUTPUT VOLTAGE (V) INPUT VOLTAGE (mV) Input overdrive : 100mV 5mV 20mV eI eo 5V 5.1kΩ Tamb = +25°C 0 0.5 1 1.5 TIME (µ s) 2 4/10 LM139,A-LM239,A-LM339,A TYPICAL APPICATIONS BASIC COMPARATOR DRIVING CMOS VCC = 5V 15kΩ +V(ref) -V(ref) +V(ref) 1/4 LM139 1/4 LM139 5V 100k Ω & VO -V(ref) DRIVING TTL LOW FREQUENCY OP AMP 5V 5V 15kΩ 10k Ω +V(ref) 1/4 LM139 ~ 1/4 LM139 eI 100kΩ & & 1kΩ A V = 100 eo 0.5µF -V(ref) LOW FREQUENCY OP AMP (e o = 0V for e I = 0V) 5V TRANSDUCER AMPLIFIER 5V 15k Ω 1/4 LM139 ~ Magnetic pick-up 10kΩ 3kΩ 2N 2222 0.5µF eI 1/4 LM139 eo 20MΩ 100kΩ 1kΩ eo A V = 100 10kΩ 5/10 LM139,A-LM239,A-LM339,A TYPICAL SINGLE (continued) TIME DEALY GENERATOR V C = +15V C 10kΩ 15kΩ 200kΩ 10MΩ 10kΩ 1/4 LM139 3kΩ V3 V O3 V CC t0 t3 3kΩ 10kΩ V CC 0t 1/4 LM139 O 51kΩ VC1 V2 0.001µF 10kΩ 10MΩ tA 1/4 LM139 V O2 V CC t0 t2 V(ref.)
