RE46C108
Description
The RE46C108 is a piezoelectric horn driver with a voltage regulator that can operate at 3.3V or 5V. It is intended for applications requiring a 9V horn driver with a low voltage logic supply. The horn feedback control pin is designed for use with selfoscillating piezoelectric horn but can also be used in direct drive applications.
