HT9315 General Description

The HT9315 series tone/pulse dialers are CMOS LSIs for telecommunication systems. They are designed to meet various dialing specifications through resistor option matrix. The HT9315 series are offered in two different versions.

They are HT9315x normal version and HT9315xL lock version, with keyboard-operated IDD lock function. The two 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.

HT9315 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 Maximum Ratings 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.
