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 80 INPUT CURRENT (nA) Tamb = -55°C Tamb = 0°C 0.8 Tamb= +25°C 0.6 Tamb = +70°C 0.4 Tamb = +125°C 0.2 R = 0 10 20 30 SUPPLY VOLTAGE (V) Tamb = +125°C -1 10 -2 10 -3 Tamb = -55°C Tamb= +25°C 10 -2 10 -1 10 0 10 1 10 OUTPUT SINK CURRENT (mA) RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - POSITIVE TRANSITION 6 1 5 4 3 2 1 0 00 50 0 OUTPUT VOLTAGE (V) INPUT VOLTAGE (mV) 20 Tamb = +125°C Tamb = +70°C 0 INPUT VOLTAGE (mV) SATURATION VOLTAGE (V) 0 10 Input overdrive : 100mV 5mV 20mV 5V 5.1kΩ eI eo Tamb = +25°C 0 0.5 1 1.5 TIME (µs) 2 Tamb= +25°C 10 20 30 SUPPLY VOLTAGE (V) 40 RESPONSE TIME FOR VAROIOUS INPUT OVERDRIVES - NEGATIVE TRANSITION Out of saturation 10 Tamb = -55°C i 40 1 10 Vi = 0V R = 10 9 Ω Tamb = 0°C 40 OUTPUT SATURATION VOLTAGE versus OUTPUT CURRENT 4/10 60 2 OUTPUT VOLTAGE (V) SUPPLY CURRENT (mA) 1 6 5 4 3 2 1 0 0 -50 -100 Input overdrive : 5mV 5V 5.1kΩ 20mV eI eo 100mV Tamb= +25°C 0 0.5 1 1.5 TIME (µs) 2 LM139,A-LM239,A-LM339,A TYPICAL APPICATIONS BASIC COMPARATOR DRIVING CMOS 5V VCC = 5V 15kΩ +V(ref) 100kΩ +V(ref) 1/4 LM139 1/4 LM139 VO & -V(ref) -V(ref) DRIVING TTL LOW FREQUENCY OP AMP 5V 5V 15kΩ 10kΩ 1/4 LM139 +V(ref) ~ 1/4 LM139 eI eo & 100kΩ -V(ref) & 0.5µF 1kΩ A V = 100 LOW FREQUENCY OP AMP (e o = 0V for e I = 0V) TRANSDUCER AMPLIFIER 5V 5V Magnetic pick-up 15k Ω 1/4 LM139 ~ eI 2N 2222 10kΩ 3kΩ 1/4 LM139 0.5µF eo 20MΩ 100kΩ eo 1kΩ 10kΩ A V = 100 5/10 LM139,A-LM239,A-LM339,A TYPICAL SINGLE (continued) TIME DEALY GENERATOR VC C = +15V 10kΩ 3kΩ 200kΩ 15kΩ 10MΩ 10kΩ 1/4 LM139 V3 V O3 VCC t0 t3 3kΩ VCC 0 t 1/4 LM139 O 10MΩ 51kΩ 10kΩ 10kΩ VC1 tA 1/4 LM139 V2 V(ref.)
