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

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, V
IN
and V
OUT
should be constrained to the range
GND
(V

or V

)

.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused outputs
must be left open.
