Product Specification

Features

General Description

•

Guard Outputs for Ion Detector Input

± 0.75pA Detect Input Current

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.

Microprocessor A/D Compatible Analog Output

Low Quiescent Current Consumption (<10uA)

Available in 8L PDIP or 8L N SOIC

2000V ESD Protection (HBM)

Available in Standard Packaging or RoHS

Compliant Pb Free Packaging

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
