IL91260C dialer equivalent, 10-memory tone/pulse dialer.
of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT sho.
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 M.
