(EOL -- HT9320K/HT9320L/HT9320L-X)
(Restricted Products -- HT9320H)
(EOL -- HT9320A  2008.5.12)

General Description

The HT9320C/D 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 version provides the LCD interface function; the HT9320K version provides the keytone function; the HT9320L version 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.

HT9320C/D series provide SA, Redial and 20 one-touch/two-touch memory dialing. If the keyboard includes M1~M20 keys it can be used as one-touch memory 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.
