W91544AN - 10-MEMORY TONE/PULSE DIALER

Download the W91544AN datasheet PDF. This datasheet also covers the W91540N variant, as both devices belong to the same 10-memory tone/pulse dialer family and are provided as variant models within a single manufacturer datasheet.

General Description

The W91540N series are tone/pulse switchable telephone dialers with 10 memories, keytone or lock function, and handfree dialing control.

These chips are fabricated using Winbond's high-performance CMOS technology and thus offer good performance in low-voltage and low-power operations.

Key Features

  • DTMF/pulse switchable dialer.
  • Two by 32-digit redial and save memory.
  • Ten by 16 digit two-touch indirect repertory memory.
  • Pulse-to-tone (.
  • /T) keypad for long distance call operation.
  • Cascaded dialing.
  • Uses 5 × 5 keyboard.
  • Easy operation with redial, flash, pause, and.
  • /T keypads.
  • Pause, P→T (pulse-to-tone) can be stored as a digit in memory.
  • 0 or 9 dialing inhibition pin for PABX system or long distance di.
