(1PC) NTE1731, ECG1731, Integrated Circuit CMOS 10 Number Pulse Dialer

This listing is for 1 integrated circuit. Description: The NTE1731 is a CMOS LSI repertory dialer with ten 16–digit number memory storage in a 16–Lead DIP type package. The pulse and mute signal outputs resulting from keyboard input are like those of a pulse dialer. The NTE1731 incorporates a 64 x 10 bit RAM which is used to store the ten telephone numbers. When used in a Public Branch Exchange (PBX) system, a Pause function is provided. This function suspends dial pulse output upon pause detection (via # key input), and resumes the output after one of the numeric keys is pressed. Features: Make Ratio: 30/40% Pin Selectable Pulse Output: “0” True Mute Output: “0” True Stores Ten 16–digit Telephone Numbers One Temporary Memory and Permanent Memory Storage of Telephone Numbers are Possible Uses a CR Oscillator as a Frequency Reference Line Operation Off–Hook, Battery Operation On–Hook Uses Either a Standard 2–of–7 Matrix Keyboard or a Single Contact Keyboard PBX Pause Storage
