SC91214/91215 SERIES
T/P SWITCHABLE DIALER WITH REDIAL HANDFREE FUNCTION
DESCRIPTION
The SC91214/15 Series is a single-chip, silicon gate, CMOS
integrated circuit with an on-chip oscillator for a 3.58MHZ crystal or
ceramic resonator. It provides a dialing pulse (DP) or dual tone multi-
frequency (DTMF) dialing. A standard 4 X4 matrix keyboard can be used
to support either DP or DTMF modes.
FEATURES
* One touch redial operation
* Tone/Pulse switchable
* 32 digit capacity for redialing
* Automatic mixed redialing (last number redial) of pulse to DTMF with
multiple automatic access pauses
* PABX auto-pause is 2.2 seconds
ORDERING INFORMATION
* DTMF Timing:
Manual dialing: minimum duration for bursts and pauses
Redialing: calibrated timing
* Hands-Free control function
* Wide operating voltage range: 2V to 5.5V
* Key-in beep tone output

* Digits dialed manually after redialing are cascadable and stored as
additional digits for the next redialing
* Uses inexpensive ceramic resonator (3.58 MHZ)
* Two versions for different telephone systems
* Built-in power up reset circuit
* Four extra function keys: flash, pause, redial and DP or DTMF mixed
dialing

Description
Oscillator Input and Output pins.
The time base for the SC91214/15 is a crystal
controlled on-chip oscillator, which is completed by
connecting a 3.58MHz crystal or ceramic
resonator between the OSCI and OSCO pins.
TRI-STATE mode select pin.
There ate two versions of the SC91214/15 as

The mode selection pin is checked for tone/pulse
dialing as each digit key entery. In the PULSE
mode, the dialing rate is checked, along with the
make/break ratio, at first key entry.

HK Hook switch input
This inverter input pin detects the state of the hook
switch contact. “Off Hook”is represented by a VDD
condition.
KT Key-in tone output
This N-channel open drain pin sends out a “beep”
tone for each PULSE mode key entry, along with
entries of accepted function keys (RD, T, F1 F2,
an P keys). The tone output frequency is 437Hz
and tone duration is 23 ms.
