DUAL COMPARATOR
MB47393
s
DESCRIPTION
The Fujitsu MB47393 is a dual comparator which is designed to operate from a single power supply over a wide
range of voltage. The input characteristics is equivalent of current industry standard comparator. Even though
operated from a single power supply, the input common mode voltage range includes ground. Owing to adoption
of clamp circuitry in input pins, mis-operation is prevented by negative input. The MB47393 is compatible with
LM393.

ABSOLUTE MAXIMUM RATINGS (see NOTE)
Ta = 25C
* : This value is specified with respect to the short circuit from output to GND. However, short circuit from the output
to V
CC
cause device destruction.
Note: Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional
operation should be restricted to the conditions as detailed in the operational sections of this data sheet.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS
(
Ta = 25C, V
CC
= 5V)
Notes:
*1: I
IN
is measured when V
I
S 0 and direction of the input current flows from IC. When negative voltage is applied
to input pin, the pin is equivalently connected the GND through a 1k
of resistor.
When low voltage below than 5V is applied, please connect a resistor serially to input pin in order to prevent
the high current flow.
*2: Positive input voltage may exceed the power supply voltage. As long as the other voltage remains in the common-
mode input voltage range, the comparator will provide a proper output state.
When V
CC
= 5V, your are requested to use V
IN
below 25V.
