13 Memory Tone/Pulse Dialer with
Handfree and Hold Function
TECHNICAL DATA
IL91350A
The IL91350A is a silicon CMOS IC that provide necessary signal for
either Pulse or Tone dialing. It features Handfree dialing, Hold, and 13
by 16 digits automatic dialing memory.
• DTMF/PULSE switchable dialer
• 32 digits for Redial memory
• Three by 16 digits for one touch direct repertory
• Ten by 16 digits for two touch indirect repertory
• Mix dialing is allowable, and the dialing length is unlimited
• Pulse to Tone (*/T) keypad for Long Distance Call operation
• Easy operation with Redial, Flash, Pause and */T keypads
• Pause, P- - >T (Pulse to Tone) can be stored as a digit in memory
• Flash time 600 mS
• 4 x 5 keyboard can be used
• Power on reset on chip

1.Flash key can not be stored as a digit in memory and
it has the first priority of the keyboard function.
2.The system will return to the initial state after the
break time is finished.
8. Mix Dialing

a.Redialing and Save dialing are valid just for first key
in.
b.The second sequence should not be operated until
the first sequence is dialed out completely.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
