W91340N SERIES
10-MEMORY TONE/PULSE DIALER WITH
HANDFREE AND HOLD FUNCTIONS
GENERAL DESCRIPTION
The W91340N series are tone/pluse switchable telephone dialers with ten memories, hold function,
and a handfree dialing control circuit. Fabricated using CMOS technology, the W91340N series offer good
performance in low-voltage and low-power applications.
FEATURES
· DTMF/pulse switchable dialer
· 32-digit redial memory
· Ten by 16-digit two-touch direct repertory memory
· Cascaded dialing allowed, with unlimited dialing length
· Pulse-to-tone (*/T) keypad for long distance call operation
· Uses 5 ´ 4 keyboard
· Easy operation with redial, flash, pause, and */T keypads
· Pause, P® T (pulse-to-tone) can be stored as a digit in memory
· Dialing rate (10 ppS or 20 ppS) is selectable by bonding option
· On-hook debounce time: 150 msec.
· Minimum tone output duration: 93 msec. (W91344AN: 87 mS)
· Minimum intertone pause: 93 msec. (W91344AN: 87 mS)
· Flash break time (73, 100, 300, 600 msec) selectable by keypad; pause time is 1.0 sec.
· Make/break ratio (40:60 or 33.3:66.7) selectable by MODE pin
· On-chip power-on reset
· Uses 3.579545 MHz crystal or ceramic resonator
· Packaged in 18 or 20-pin plastic DIP

Column-
Row Inputs
The keyboard inputs may be used with either a standard
5 ´ 4 keyboard or an inexpensive single contact (Form A)
keyboard. Electronic input from a mC can also be used.
A valid key is defined as a single row being connected to a
single column.

Pulling mode pin to VSS places the dialer in tone mode.
Pulling mode pin to VDD places the dialer in pulse mode
with M/B ratio of 40:60 (10 ppS, except for
W91342N/W91342AN = 20 ppS.)
Floating mode pin places the dialer in pulse mode with M/B
ratio of 33.3:66.7 (10 ppS, except for W91342N/W91342AN
= 20 ppS.)

HKS = VSS: Off-hook state. Chip is enabled for normal
operation.
HKS pin is pulled to VDD by an internal resistor.
