IL91531 ETC - PARALLEL INPUT TONE/PULSE DIALER HIGH-PERFORMANCE SILICON-GATE CMOS

IL91531 PARALLEL INPUT TONE, PULSE DIALER HIGH-PERFORMANCE SILICON-GATE CMOS 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 stan
