LM393SNG ON Semiconductor

LM393S, LM2903S Low Offset Voltage Dual Comparators The LM393S and LM2903S are dual, independent, precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range to ground level LM393S, LM2903S MAXIMUM RATINGS Rating Symbol Value Unit Power Supply Voltage V +36 or 18 V CC Input Differential Voltage V 36 V IDR Input Common Mode Voltage Range (Note 1) V 0.3 to +36 V ICR Output Voltage V 36 V O Output Short CircuittoGround I Continuous mA SC Output Sink Current (Note 2) I 20 Sink Power Dissipation T = 25C P 570 MW A D Derate above 25C 1/R 5.7 mW/C JA Operating Ambient Temperature Range T C A LM393S 0 to +70 LM2903S 40 to +105 Maximum Operating Junction Temperature T 150 C J(max) Storage Temperature Range T 65 to +150 C stg Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. For supply voltages less than 36 V, the absolute maximum input voltage is equal to the supply voltage. 2. The maximum output current may be as high as 20 mA, independent of the magnitude of V , output short circuits to V can cause CC CC excessive heating and eventual destruction.
