TECHNICAL DATA IL91531 PARALLEL INPUT TONE/PULSE DIALER High-Performance Silicon-Gate CMOS The IL91531 provides a 4-bit data input and a handshaking signal to serve as microcomputer interfaces. Under microcomputer control the IL91531 generates both a DTMF signal and a pulse output for telephone dialing. All necessary dual-tone frequencies and dial pulse outputs are derived from the widely used TV crystal standard, providing high accuracy and stability. The required sinusoidal waveform for indi.
