OUTPUTS DESCRIPTION These devices consist of four independent precision voltage comparators with an offset voltage specifications as low as 2mV max for LM339A, LM239A and LM139A. 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. PIN CONNECTIONS (top view)

Short-circ uits from the output to VCC + can cause excessive heating and eventual destruction. The maximum output current is approximately 20mA independent of the magnitude of VCC + . Pd is calculated with T amb = +25°C, Tj = +150°C and R thja = 80°C/W for DIP14 package = 150°C/W for SO14 package = 175°C/W for TSSOP14 package

At output switch point, Vo 1.4V, R s = 0 with VCC from 5V to 30V, and over the full common-mode range (0V to VCC -1.5V). T he 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. T he 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 T he response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained Pos istiv e 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).
