com R&E International RE46C112 Ionization Smoke Detector IC Product Specification General Description The RE46C112 is an ionization type smoke detector IC.
It is intended for applications using ionization type chambers to detect smoke.
When enabled, VOUT is ¼ of either the DETECT input or VDD depending on the status of the SELECT input.
When the Select input is allowed to float the circuit is in the low current mode with only the guard amplifier enabled.
Utilizing low power CMOS technology the RE46C112 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217.
Features • • • • • • • Guard Outputs for Ion Detector Input ± 0.

3 -10 to 60 -55 to 125 150 UNITS V V V V °C °C °C Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.
These are stress ratings only and operation at these conditions for extended periods may affect device reliability.
This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used when handling this product.
Damage can occur when exposed to extremely high static electrical charge Telephone 610.
