Low–Power CMOS
ALARM IC
with Horn Driver
The MC14600 Alarm IC is designed to simplify the process of interfacing an
alarm level voltage condition to a piezoelectric horn and/or LED. With an extremely
low average current requirement and an integrated low battery detect feature, the
part is ideally suited to battery operated applications. The MC14600 is easily
configured with a minimum number of external components to serve a wide range
of applications and circuit configurations. Typical applications include intrusion
alarms, moisture or water ingress alarms, and personal safety devices.
• High Impedance, FET Input Comparator
• Comparator Outputs for Low Battery and Alarm Detect
• Alarm Detect Threshold Easily Established with 2 Resistor
• Integrated Oscillator and Piezoelectric Horn Driver
• Low Battery Trip Point Set Internally (Altered Externally)
• Horn “Chirp’’ During Low Battery Condition
• Pulsed LED Drive Output
• Reverse Battery Protection
• Input Protection Diodes on the Detect Input
• Average Supply Current: 9 µA

* Maximum Ratings are those values beyond which damage to the device may occur.
This device contains circuitry to protect the inputs against damage due to high static voltages
or electric fields; however, it is advised that normal precautions be taken to avoid application
of any voltage higher than maximum rated voltages to this high impedance circuit. For proper
voperation it is recommended that Vin and Vout be constrained to the range VSS (Vin or Vout)
v VDD.

NOTES:
1. Horn modulation is self–completing. When going from Alarm to No Alarm, the alarm condition will terminate only when horn is off.
2. Comparators are strobed once per cycle.
3. Low battery comparator information is latched only during LED pulse.
4. Current source required into Pin 1.
5. Alarm Condition can initiate on any clock pulse except 1 and 7.
