NTE1731 - Integrated Circuit CMOS 10 Number Pulse Dialer

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.

NTE1731 Integrated Circuit CMOS 10 Number Pulse Dialer 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.
