GENERAL DESCRIPTION
The W91330N series are Si-gate CMOS ICs that provide the necessary signals for tone or pulse
dialing. They feature one-key redial, handfree dialing, key tone, redial, and lock functions.
FEATURES
Pulse-to-tone (*/T) keypad for long distance call operation
Uses 5
Minimum intertone pause: 93 msec.
On-chip power-on reset
DTMF/pulse switchable dialer
32-digit redial memory
Easy operation with redial, flash, pause, and */T keypads
Pause, pulse-to-tone (*/T) can be stored as a digit in memory
Dialing rate (10, 20 ppS ) selected by bonding option
Minimum tone output duration: 93 msec.
Flash break time (73, 100, 300, 600 msec.) selectable by keypad; pause time is 1.0 sec.
Uses 3.579545 MHz crystal or ceramic resonator
Packaged in 18 or 20-pin plastic DIP
The different dialers in the W91330N series are shown in the following table:
0 or 9 dialing inhibition pin for PABX system or long distance dialing lock out
Off-hook delay 300 mS in lock mode ( DP will keep low for 300 mS low while off hook)
First key-in delay 300 mS output in lock mode
