TECHNICAL DATA
10 Memory Tone/Pulse Dialer
High-Performance Silicon-Gate CMOS
IL91260C
The IL91260C is tone/pulse switchable dialer with ten 16-digit number
memories and 32-digit redial memory. Pulse to tone mode switching is
performed via a slide switch.
• 32-digit redial memory (31 digits in tone mode)
• Ten indirect memories, 16 digits in pulse mode, 15 digits in tone
mode
• Tone/Pulse mode switching via slide switch (4.1 second pause
inserted automatically)
• Wide operating voltage: 1.8 V ∼ 5.5 V
• Uses 480 KHz ceramic resonator
• Low memory retention current
• Selectable Make/Break ratio
• Dial Pulse Rate: 10 pps

Note 1:
DIS% =
100.(V12 + V22 +. . . + Vn2)1/2
(VOC2 + VOR2)1/2
a. V1 . . . Vn are the intermodulation or the harmonic frequencies in the 500 Hz to 3400 Hz band.
b. VOC and VOR are the individual frequency components of the DTMF signal.
