IL91260C 10-Memory Tone/Pulse Dialer

Pin No. 1 2 3 4 5 Designation R1 R2 R3 R4 HK Hook switch input. When HK = VCC, an ON-Hook state exists. When HK = GND, an Off-Hook state exists. Dial pulse Make/Break ratio select input. If M/B = VCC , the Make/Break ratio is 1/2. If M/B = GND, the Make/Break ratio is 2/3. Pulse/DTMF mode select inp.

TECHNICAL DATA IL91260C 10 Memory Tone/Pulse Dialer High-Performance Silicon-Gate CMOS 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) .
