1-MEMORY/2-MEMORY TONE/PULSE
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.
