W91330N SERIES
TONE/PULSE DIALER WITH HANDFREE
LOCK AND KEY TONE FUNCTIONS
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
·
DTMF/pulse switchable dialer
·
32-digit redial memory
·
Pulse-to-tone (*/T) keypad for long distance call operation
·
Uses 5 ´ 4 keyboard
·
Easy operation with redial, flash, pause, and */T keypads
·
Pause, pulse-to-tone (*/T) can be stored as a digit in memory
· 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
·
Dialing rate (10, 20 ppS ) selected by bonding option
·
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 1.0 sec.
·
On-chip power-on reset
·
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:

The function of this terminal is to prevent "0" dialing
and "9" dialing under PABX system long distance
call control. When the first key input after reset is 0
or 9, all key inputs, including the 0 or 9 key, become
invalid and the chip generates no output. The
telephone is reinitialized by a reset.
