General Description

The HT9302 series tone/pulse dialers are CMOS LSIs

for telecommunication systems. They are designed to

meet various dialing specifications through resistor op-

tion matrix.

The HT9302 series provide the pin-selected lock func-

tion, 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.
