ET-LM393
Dual Differential Comparators
Description
The ET-LM393 consists of two independent
voltage comparators. These were designed
specifically to operate from a single power
supply over a wide range of voltages. Operation
from split power supplies is also possible and
the low power supply current drain is
independent of the magnitude of the power
supply voltage. The outputs can be connected to
other open-collector outputs to achieve
wired-AND relationships.
Features
¾ Low Supply Current Drain Independent of The
Supply Voltage.
¾ Low Input Biasing Current.
¾ Low Input Offset Current.
¾ Low Input Offset Voltage.
¾ Input Common-Mode Voltage Range Includes
GND.
¾ Differential Input Voltage Range Equal To The
Power Supply Voltage.
¾ Low Output Saturation Voltage.
¾ Output Voltage Compatible With TTL, MOS
and CMOS Logic.
