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 dela y 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

Maximum Ratings are those values beyond which damage to the device may occur.
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.

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 V
OUT
should be constrained to the range
GND≤(VIN or V
OUT
)≤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.
