DIALER

DESCRIPTION

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 pin-

selected 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.
