W91610 SERIES
TONE/PULSE DIALER WITH
TWO-STAGE REDIAL FUNCTION
GENERAL DESCRIPTION
The W91610 series are Si-gate CMOS ICs that provide the signals needed for either pulse or tone
dialing.
FEATURES
DTMF/Pulse switchable dialer
32-digit redial memory
Two-stage redial function
Pulse-to-tone (PT) keypad for long distance call operation
Easy operation with redial, flash, pause and PT keypads
Pause, pulse-to-tone (PT) can be stored as a digit in memory
Tone output duration: as long as key is depressed or 90 mS minimum
Minimum intertone pause: 90 mS
Flash time: 100 mS
Uses 4 × 5 keyboard
On-chip power-on reset
Uses 3.579545 MHz crystal or ceramic resonator
Packaged in 18-pin DIP
The different dialers in the W91610 series are shown in the following table:

I Keyboard inputs are designed for use with either a standard 4 × 5
keyboard or an inexpensive single contact (Form A) keyboard.
Electronic input from a µC can also be used.
Valid key entry is defined by a connection between a single row
and a single column.
I, O A built-in inverter provides oscillation with an inexpensive
3.579545 MHz crystal or ceramic resonator.
O The T/P MUTE is a conventional CMOS inverter output. It is low
during pulse and tone mode dialing sequence and flash break;
otherwise, it remains high.
I Pulling the mode pin to VSS place the dialer in tone mode.
Pull to VDD or leave floating: Pulse mode (10 ppS, M/B = 2:3 or
1:2)

Pin Description, continued
SYMBOL PIN NO. I/O
FUNCTION
HKS
10 I Hook switch input. Conventional CMOS input with an internal
protection diode and a pull-high resistor to VDD.
HKS = VDD: On-hook state. Chip in sleep mode, no operation.
HKS = VSS: Off-hook state. Chip enabled for normal operation.
During dialing, this input ignores HKS = VDD for durations of less
than 150 mS (i.e., dialing is not terminated).
DP /C5
11 O Open drain dialing pulse output (Figure 1).
Flash key causes DP /C5 to be active in both tone mode and pulse
mode.
DTMF
12 O During pulse dialing, maintains low state at all times.
In tone mode, outputs a dual or single tone.
Detailed timing diagram for tone mode is shown in Figure 2(a, b).
