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

lock function. The six versions also supply the hold-line

and hand-free functions, which are suitable for feature

phone applications.

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.
