General Description
The HT9320 series tone/pulse dialers are CMOS LSI for
telecommunication systems. They are designed to meet
various dialing specifications through resistor option
matrix.
The HT9320 series are offered in six different versions.
The different functions of the six versions are listed in
the selection table. The HT9320A, HT9320H versions
provide the on-hook store function; the HT9320B ver-
sion provides the LCD interface function; the HT9320K
version provides the keytone function; the HT9320L ver-
sion provides both the LCD interface function and IDD

one-touch/two-touch memory dialing. If the keyboard in-
cludes M1~M20 keys it can be used as one-touch mem-
ory dialing. Otherwise, it works as two-touch
(PAGE®M1~M10) or three-touch(A®PAGE®0~9)
memory dialing for speed dialing in either pulse or tone
mode.
