When a key is depressed, scanning signals are presented at C1, C2, and C3 inputs; the dialer identifies th.
TECHNICAL DATA IL9151-3 PULSE DIALER The IL9151-3 pulse dialer is a monolithic CMOS integrated circuit which converts pushbutton inputs to a series of pulses suitable for telephone dialing. It is intended to replace mechanical telephone dialers and can operate directly from telephone lines. CMOS technology is used to produced this device, resulting in very low power requirements and high noise immunity. The IL9151-3 can be easily interfaced with a variety of telephones, requiring only a minima.
