RE46C160
CMOS Alarm ASIC
Preliminary Product Specification
General Description
The RE46C160 is a low power CMOS general purpose
alarm detector IC which provides an interface to a
piezoelectric horn and LED for signaling and
notification. With a few external components this IC can
provide many features for a variety of alarm
applications. In addition low standby current makes this
circuit ideal in battery powered applications.
Typical applications include personal, home and auto
anti-theft type alarms and liquid level or temperature
sensing alarms.
An internal oscillator strobes power to the 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.

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
