MC14600
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.

* 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
operation it is recommended that Vin and Vout be constrained to the range VSS (Vin or Vout)
VDD.
