>1500V ESD Protection (HBM) on all Pins  
The RE46C122 is low power CMOS ionization type  
smoke detector IC. With few external components this  
circuit will provide all the required features for an  
ionization type smoke detector.  
Guard Outputs for Ion Detector Input  
+/-0.75pA Detect Input Current  
Internal Reverse Battery Protection  
Low Quiescent Current Consumption (<6.5uA)  
Available in 16L PDIP or 16L N SOIC  
Internal Low Battery Detection  
An internal oscillator strobes power to the smoke  
detection circuitry for 10.5mS every 1.66 seconds to  
keep standby current to a minimum. A check for a low  
battery condition is performed every 40 seconds when  
in standby. The temporal horn pattern supports the  
NFPA 72 emergency evacuation signal.  
Power Up Low Battery Test  
Interconnect up to 40 Detectors  
10 Minute Timer for Sensitivity Control  
Compatible with Allegro A5367  
UL Recognized per File S24036  
Available in Standard Packaging or RoHS  
Compliant Pb Free Packaging.  
Pin Configuration  
An interconnect pin allows multiple detectors to be  
connected such that when one units alarms all units will  
sound.  
An internal 10 minute timer allows for a separate button  
to be used for reduced sensitivity mode.

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.
