LM239QT

LM139, LM239, LM339 Low-power quad voltage comparators Datasheet - production data Features • Wide single supply voltage range or dual supplies for all devices: +2 to +36 V or ±1 V to ±18 V D SO14 (plastic micropackage) • Very low supply current (1.1 mA) independent of supply voltage • Low input bias current: 25 nA typ • Low input offset current: ±5 nA typ • Low input offset voltage: ±1 mV typ P TSSOP14 (thin shrink small outline package) • Input common-mode voltage range includes ground • Low output saturation voltage: 250 mV typ; (ISINK = 4 mA) • Differential input voltage range equal to the supply voltage • TTL, DTL, ECL, MOS, CMOS compatible outputs Q QFN16 3x3 (plastic micropackage) Description This family of devices consists of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV maximum for LM339A, LM239A, and LM139A. Each comparator has been designed specifically to operate from a single power supply over 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.

Short-circuits from the output to VCC+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20 mA independent of the magnitude of VCC+. 2. Short-circuits can cause excessive heating. These values are typical. 3. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 4. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating. 5. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 4/19 DocID2159 Rev 4 LM139, LM239, LM339 Absolute maximum ratings and operating conditions Table 2.

LM139 - LM239 LM339 Min Typ. Unit Max. 300 ns 1. At output switch point, Vo ≈ 1.4 V, VCC+ from 5 V to 30 V, and over the full common-mode range (0 V to VCC+ -1.5 V). 2. 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. 3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is VCC+ -1.5 V, but either or both inputs can go to +30 V without damage. 4. Positive 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 -0.3 V (or 0.3 V below the negative power supply, if used). 5. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals, 300 ns can be obtained. DocID2159 Rev 4 7/19 19 Electrical characteristics curves 4 LM139, LM239, LM339 Electrical characteristics curves Figure 3.
