15-MEMORY TONE/PULSE DIALERS WITH VOLUME SWITCHES

The SC9315XV series Tone pulse dialers are CMOS LSIs for the telecommunication system. They are designed to meet various dialing specifications through resistor options matrix. Aside from basic dialing functions, this series also provides two switches for speech circuit Volume Control or for auxiliary controls. The switches are operated with 4 keys on the keyboard matrix for < toggle /cyclical / up / down > speech Volume Control A 4-step volume CAN be switched with the initial volume set by the option resistors connected on the keyboard matrix. Similar to the normal series, this series also supply the following functions: Hold-line, Hand-free and LCD feature phone applications. By Silan
