RE46C114
Ionization Smoke Detector IC
Product Specification
General Description
The RE46C114 is an ionization type smoke detector IC.
It is intended for applications using ionization type
chambers to detect smoke. When enabled, VOUT is
1/2 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 RE46C114
was designed for use in smoke detectors that comply
with Underwriters Laboratory Specification UL217.

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
