Download the W9145A datasheet PDF (W9145 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for 15-memory tone/pulse dialer.

Description

The W9145 series are Si-gate CMOS ICs that provide the necessary signals for either pulse or tone dialing.

The W9145 series feature a key tone function, handfree dialing, a lock function, thirteen 16digit automatic dialing memories, and two by 32-digit for redial and save memory.

Features

  • DTMF/Pulse switchable dialer.
  • Two by 32 digits for redial and save memory.
  • Three by 16 digits for one-touch direct repertory.
  • Ten by 16 digits for two-touch indirect repertory.
  • Unlimited dialing length (redial inhibited if dialing length exceeds 32 digits in normal dialing).
  • Auto Pause Access for PBX and toll service operations (3.1 seconds per pause).
  • Easy operation with redial, store, auto and pause keypads.
