W91430N SERIES

13-MEMORY TONE/PULSE DIALER

WITH SAVE FUNCTION

GENERAL DESCRIPTION

The W91430N series are Si-gate CMOS ICs that provide the necessary signals for either tone or

pulse dialing. The W91430N series features save memory and a 13 by 16 digit automatic dialing

memory.

FEATURES

· DTMF/pulse switchable dialer

· Two by 32 digit redial and save memory

· Three by 16 digit one-touch direct memory

· Ten

by 16 digit two-touch direct memory

· Redial memory cascadable with normal dialing; dialing length is unlimited, but if length oversteps

32-digit the redial function is inhibited

Pulse-to-tone (*/T) keypad for long distance call operation

Uses 5 ´ 5 keyboard

Easy operation with redial, flash, pause and */T keypads

Flash, pause, P® T (Pulse-to-tone) can be stored as a digit in memory

Dialing rate (10, 20 ppS ) selected by bonding option

· On hook debounce time: 150 msec.

Minimum tone output duration: 93 msec.

Minimum intertone pause: 93 msec.

Flash break time (73, 100, 300, 600 msec.) selectable by keypad; pause time is 1 sec.

On-chip power-on reset

Uses 3.579545 MHz crystal or ceramic resonator

Packaged in 18-pin plastic DIP
