KS58006
TONE/PULSE DIALER WITH REDIAL
INTRODUCTION
The KS58006 is DTMF/PULSE switchable dialer with a 32-digit redial which
can be done using a slide switch. All necessary dual-tone frequencies are
derived from a 3.579545 MHz TV crystal or ceramic resonator providing very
high accuracy and stability. The required sinusoidal wave form for each in-
dividual tone is digitally synthesized on the chip. The generated wave form
has very low total harmonic distortion (7% max). A voltage reference is
generated on the chip which is stable over the operating voltage and tem-
perature range and regulates the single levels of the dual tone to meet telephone
industry specifications. CMOS technology is applied to this device, for very
low power requirements high noise immunity, and easy interface to a variety
of telephones requiring external components.
18-DIP-300A
FEATURES
• Tone/Pulse switchable (slide switch)
• 32-digit capacity for redial
• Automatic mix redialing ( last number dial ) of
PULSE → DTMF with multiple auto access pause
• PABX auto-pause for 3.5 sec.
• 4 X 4 or ( 2 of 8 ) keyboard available
• Two key single tone operation
• Operating Voltage : 2.0 ~ 5.5V
• Numbers dialed manually after redial are cascadable
and stored as additional numbers for next redialing
• Uses inexpensive TV crystal or ceramic resonator
(3.579545MHz)
• Make/Break ratio (33.3 / 66.6) pin selectable
• Touch key hooking (604ms)
• Low standby current
• Improved EMI characteristic
• Improved redial memory quality

TONE/PULSE DIALER WITH REDIAL
APPLICATION INFORMATION
KEYBOARD OPERATION
1. SINGLE MODE OPERATION
Pulse Mode Operation
Off Hook
D1 . . . Dn
The pulse mode is defined by the initial mode after going off Hook and latched at D1 key entry. This is the condition
under MDS = VDD.
Tone Mode Operation
Off Hook
D1 . . . Dn
The tone mode is defined by the initial mode after going off Hook and latched at D1 key entry. This is the condition
under MDS = VSS.
Manual Dialing with Automatic Access Pause
Off Hook
D P D1
. . . Dn
Multiple Pause key entries can be accepted and stored in the redial memory, each as a digit. Each P key provides
3.5 seconds pause time, but the P key entry as the first digit after going Off Hook is ignored. The * key can also
be used as a pause key in the pulse mode. Pause (2) can be cancelled with the P or RD key during pause time
in redialing.
D = Any numeric key.
Redialing
Off Hook
RD
Up to 32 digits can be dialed with the RD key. The RD key is disabled while pulse or DTMF signals are transmitted.
When more than 32 digits are stored, redial is also inhibited.
The # key can be used as the RD key in the pulse mode.
Inhibiting Redial
Off Hook
D1 . . . Dn RD RD
Redial can be inhibited by depressing the RD key twice after DTMF or pulse signals are transmitted.
