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.
