SC9302

The SC9302 series tone/pulse dialers are CMOS LSIs for the telecommunication system. They are designed to meet various dialing specifications through resistor options matrix.

The SC9302 series tone/pulse dialers are offered in four different versions. They are SC9302X normal version, SC9302/F/G/H simple version, SC9302XT key-tone version and SC9302XLT key-tone/lock functions version. The SC9302X normal version provides the pinselected lock function; the SC9302XT version provides the key-tone function; the SC9302XLT version provides both the key-tone function and key board-operated IDD lock function. All of the above three
versions also supply the following functions: Hold-line, Hand-free and LCD dialing number display interface, all of which are suitable for feature phone applications. However, the SC9302F/G/H version is simpler than the other three versions. It provides only a redialing memory for a simple low-cost system application.
