IL91210EN
TONE/PULSEDIALER
The IL91210EN is a single-chip, silicon gate, CMOS integrated circuit with an on-chip oscillator for a
3.58 MHz crystal or ceramic resonator. It provides dialing pulse (DP) or dual tone multi-frequency
(DTMF) dialing. A standard 4x4 matrix keyboard can be used to support either DP or DTMF modes.
Up to 32 digits can be saved in the on-chip RAM for reading. In the DTMF mode, minimum tone
duration and minimum intertone pause are provided for rapid
dialing. Maximum tone duration is dependent upon the key
depression time in manual dialing.
• One touch redial operation
• Tone/Pulse switchable
• 32-digit capacity for redialing
• Built-in power up reset circuit
• PABX auto-pause is 2.2 second
• DTMF Timing:
Manual dialing: minimum duration for bursts and pauses
Redialing: calibrated timing
ORDERING INFORMATION
IL91210EN
TA = -20° to 70° C
• Wide operating voltage range: 2 V to 5.5 V
• Uses inexpensive ceramic resonator (3.58 MHz)
• Digits dialed manually after redialing are cascadable and stored as additional digits for the next
redialing
• Automatic mixed redialing (last number redial) of pulse to DTMF with multiple automatic access
pauses
• Four extra function keys: flash, pause, redial and DP or DTMF mixed dialing
• Four-by-four (or 2 of 8) keyboard can be used
• Low standby current
• Dial Pulse Rate: 10 pps
