The RE46C190S16F is a low-power, low-voltage CMOS photoelectric smoke detector integrated circuit designed for use in smoke detection applications. It operates on two AA batteries and features an internal power-on reset, low quiescent current consumption, and a local alarm memory. The device supports interconnection of up to 40 detectors, allowing for simultaneous alarm activation across multiple units. Key functionalities include a nine-minute timer for sensitivity control, an internal low battery and chamber test, and an adjustable infrared emitter diode (IRED) drive current. The RE46C190 also offers a temporal or continuous horn pattern for alarms, and it is compliant with Underwriters Laboratory specifications UL217 and UL268. The product is packaged in a 16-lead narrow SOIC format. However, it is important to note that the RE46C190 is not recommended for new designs, with the RE46C191 being the suggested alternative.
