SL393 Low Power Low Offset Voltage Dual Comparators The SL393 consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. • Single or Split Supply Operation • Low Input Bias Current • Low Input Offset Current • Input Common Mode Voltage Range to Gnd • Low Output Saturation Voltage • TTL and CMOS Compatible ORDERING INFORMATION SL393N Plastic SL393D SOIC TA = 0° to 70° C for all packages.

Functional operation should be restricted to the Recommended Operating Conditions. Notes: 1. Split Power Supplies. 2. VIN<-0.3V. This input current will only exist when voltage at any of the input leads is driven negative. RECOMMENDED OPERATING CONDITIONS Symbol Parameter VCC DC Supply Voltage TA Operating Temperature, All Package Types Min Max Unit ±2.5 or 5.0 ±15 or 30 V 0 +70 °C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
