General Description
The HT9315 series tone/pulse dialers are CMOS LSIs for
telecommunication systems. They are designed to meet
various dialing specifications through resistor option ma-
trix.
The HT9315 series are offered in two different ver-
sions. They are HT9315x normal version and
HT9315xL lock version, with keyboard-operated IDD
lock function. The two versions also supply the follow-
ing functions: Hold-line, Hand-free and LCD dialing
number display interface, all of which are suitable for
feature phone applications.
