NT91215 - Tone / Pulse Dialer

This page provides the datasheet information for the NT91215, a member of the NT91214 Tone / Pulse Dialer family.

Description

The NT91214/15 is a single-chip, silicon gate, CMOS integrated circuit with an on-chip oscillator for a 3.58MHz crystal or ceramic resonator.

It provides a dialing pulse (DP) or dual tone multi-frequency (DTMF) dialing.

A standard 4 x 4 matrix keyboard can be used to support either DP or DTMF modes.

Features

T One touch redial operation T Tone/Pulse switchable T 32 digit capacity for redialing T Automatic mixed redialing (last number redial) of pulse T PABX auto-pause is 2.2 seconds T DTMF Timing: T to DTMF with multiple automatic access pauses Manual dialing: minimum duration for bursts and pauses Redialing: calibrated timing Hands-Free control function T Wide operating voltage range: 2V to 5.5V T Key-in beep tone output T Digits dialed manually after redialing are T T T T cascadable and stored.
