W91580 SERIES
24-MEMORY TONE/PULSE SWITCHABLE DIALER
WITH HANDFREE AND HOLD FUNCTIONS
GENERAL DESCRIPTION
The W91580 series dialers are Si-gate CMOS IC tone/pulse switchable dialers containing a 24-
channel automatic dialing memory, including a 16-digit × 3 emergency dialing memory, a 16-digit ×
20 channel repertory memory that provides one-touch and three-touch dialing, and a 32-digit mercury
memory. These dialers also provide flash, clear, hold, and one-key redial functions.
FEATURES
DTMF/Pulse switchable dialer
31/32-digit LNB (last number buffer) memory (tone/pulse mode)
31/32-digit mercury memory (tone/pulse mode)
15/16-digit × 3 one-touch direct repertory memory (tone/pulse mode)
15/16-digit × 20 direct or indirect repertory memory (tone/pulse mode)
Uses 9 × 5 keyboard
Flash time: 98 mS, 305 mS, or 600 mS (selectable by keypad option)
Pause time: 3.6 sec.
Pause and PT (pulse-to-tone) can be stored as a digit in memory
Minimum tone output duration: 100 mS
Minimum intertone pause: 100 mS
On-chip power-on reset
Uses 3.579545 MHz crystal or ceramic resonator
Packaged in 22, 24, or 28-pin plastic DIP

I/O FUNCTION
I The keyboard input may be used with either the
standard 9 × 5 keyboard or an inexpensive
single contact (form A) keyboard. Electronic
input from a µC can also be used.
A valid key entry is defined by a single row
being connected to 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
N-channel open drain output.
The output transistor is switched on during pulse
and tone mode dialing sequence and flash
break. Otherwise, it is switched off.
O The HPM MUTE is a conventional inverter
output. During pulse dialing, flash, hold, and
mercury mute functions, this pin will output an
active high. It remains in a low state at all other
times.
