The is an analog building block consisting of a veryhigh input impedance comparator. The voltage follower allows monitoring the noninverting input of the comparator without loading. Four enhancementmode MOSFETs are also included on chip. These FETs can be externally configured as opendrain or totempole outputs. The drains have onchip staticprotecting diodes. Therefore, the output voltage must be maintained between VSS and VDD. The chip requires one external component. M 10% resistor must be connected from the Rbias pin to VDD. This circuit is designed to operate in smoke detector systems that comply with UL217 and UL268 specifications.

*Maximum Ratings are those values beyond which damage to the device may occur. 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 highimpedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS (Vin or Vout) VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either SS or VDD). Unused outputs must be left open.
