Exposure to absolute maximum rating conditions for extended periods may affect reliability. Functional operation of the device at any conditions beyond those indicated in the Recommended Operating Conditions section is not implied. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because even small parametric changes could cause the device not to meet the published specifications. SOT-23-5/SC70-5 This integrated circuit can be damaged if ESD protections are not considered carefully. SGMICRO recommends that all integrated circuits be handled with appropriate precautions.

The device supports rail-to-rail input operation. It is suitable for portable equipment. Open-drain structure needs external pull-up resistor. The SGM8749 can be compatible with CMOS and TTL logics. If low slew rate transition is needed in system design, adjusting the load capacitance will change the slew rate. The heavier capacitive load will slow down the output voltage transition. This feature will be used to reduce the interference generated by fast edge of transition between 1 and 0 in noise-sensitive system. VCC Output Structure In Figure 1, the SGM8749 has an open-drain output stage. When output is changed from logic high to low, the changed sink current pulls output pin to logic low. Beginning this transition, larger sink current is used to create a high slew rate transit from high to low. Once the output voltage reaches VOL, it will reduce the sink current to a just right value to maintain the VOL static condition. This current-driven open-drain output stage will significantly reduce the power consumption in application system. 4.7kΩ Output GND ISINK Figure 1.

This ceramic capacitor must be placed as close to VCC pin as possible.  For grounding, unbroken and low-inductance ground plane is a good choice.  For Layout, use short PCB trace to avoid unwanted parasitic feedback around the comparator. SGM8749 must be soldered directly to the PCB and the socket is not recommended. 3V 20kΩ 0 Figure 3.
