Note: These are stress ratings only. Stresses exceeding the range specified under  Absolute Maximum Ratings  may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

The HT9302 series tone/pulse dialers are CMOS LSIs for telecommunication systems. They are designed to meet various dialing specifications through resistor option matrix.

The HT9302 series provide the pin-selected lock function, Hold-line, Hand-free and LCD dialing number display interface, all of which are suitable for feature phone applications. HT9302G is simpler than HT9302X version. It provides only a redialing memory for simple low-cost system applications.
