TELEPHONE TONE RINGER
GENERAL DESCRIPTION
The UTC 31001 is a bipolar integrated circuit
designed for telephone bell replacement. It can also be
used as alarms or other alerting devices.
FEATURES
*Designed for telephone bell replacement.
*Low current drain for multiple extention of lines.
*Adjustable 2-frequency tone.
*Adjustable warbling rate.
*Bulit-in hysteresis prevents false triggering and
rotary dial 'CHIRPS'.
*Programmable for initiation voltage by simple
external resistor
