Part Number : IL91531
Function : PARALLEL INPUT TONE/PULSE DIALER / HIGH-PERFORMANCE SILICON-GATE CMOS
Maker : Integral

Pinouts :
IL91531 datasheet

Description :

The IN91531N provides a  4-bit data input and a handshaking signal to serve as microcomputer interfaces. Under microcomputer control the IN91531N 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 individual tones is digitally synthesized on the chip, resulting in a waveform with very low total harmonic distortion.
