General Description
HT9302 Series General Description
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 numberdisplay 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.
