Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of JEDEC)
Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).
Note 3: The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(MAX) - TA)/ θJA . All numbers apply for packages soldered directly onto a PC board.
Note 4: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will
also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material.
Note 5: All limits are guaranteed by testing or statistical analysis.
Note 6: The input common-mode voltage of either input should not be permitted to go below the negative rail by more than 0.3V. The upper end of the common-
mode voltage range is VS - 1.5V at 25°C.

Input Stage
The SM73403 has a bipolar input stage. The input common
mode voltage range is from 0 to (VS – 1.5V).
Output Stage
The SM73403 has an open collector grounded-emitter NPN
output transistor for the output stage. This requires an exter-
nal pull-up resistor connected between the positive supply
voltage and the output. The external pull-up resistor should
be high enough resistance so to avoid excessive power dis-
sipation. In addition, the pull-up resistor should be low enough
resistance to enable the comparator to switch with the load
circuitry connected. Because it is an open collector output
stage, several comparator outputs can be connected together
to create an OR’ing function output. With an open collector,
the output can be used as a simple SPST switch to
ground.The amount of current which the output can sink is
approximately 10mA. When the maximum current limit is
reached, the output transistor will saturate and the output will
rise rapidly (Figure 4).
