RE46C160

CMOS Alarm ASIC

Preliminary Product Specification

Features

General Description

•

Guard Outputs for Detect Input

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

Low leakage MOSFET input comparator

Internal Reverse Battery Protection

Internal Low Battery Detection

Low Quiescent Current Consumption (<6uA)

Available in 16L PDIP or 16L N SOIC

ESD Protection on all Pins

applications. In addition low standby current makes this

circuit ideal in battery powered applications.

Compatible with MC14600

Typical applications include personal, home and auto

anti-theft type alarms and liquid level or temperature

sensing alarms.

Pin Configuration

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.

Maximum Junction Temperature

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
