HT9320 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 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.

HT9320 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 (PAGEM1~M10) or three-touch(APAGE0~9) memory dialing for speed dialing in either pulse or tone mode.

HT9320 Maximum Ratings

Supply Voltage ................................-0.3V to 6V
Input Voltage .................. V_SS-0.3 to V_DD+0.3V
Storage Temperature ............. .-50 to 125
Operating Temperature .............-20 to 75

Note: These are stress ratings only. Stresses exceeding the range specified under Absolute MaximumRatings may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
