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.
