RE46C145
CMOS Photoelectric Smoke Detector ASIC with Interconnect and Timer Mode
Product Specification
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.
Note 1: Does not include Q3 emitter current.
