SC91214D - TONE/PULSE DIALER

Download the SC91214D datasheet PDF. This datasheet also covers the SC91214 variant, as both devices belong to the same tone/pulse dialer family and are provided as variant models within a single manufacturer datasheet.

General Description

The SC91214/15 Series 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 multifrequency (DTMF) dialing.

Key Features

  • One touch redial operation.
  • Tone/Pulse switchable.
  • 32 digit capacity for redialing.
  • Automatic mixed redialing (last number redial) of pulse to DTMF with multiple automatic access pauses.
  • PABX auto-pause is 2.2 seconds.
