f f M 751 tOS/MOS INTEGRATED CIRCUIT f---------------------------------------------------------------- PRELIMINARY DATA ~OUCH TONE GENERATOR f' 2.5 to 5V SUPPLY :. INTERNAL PULL-UP WITH DIODE PROTECTION ON ALL INPUTS ,. ON CHIP CRYSTAL CONTROLLED OSCILLATOR: 4.433619 MHz • INTERNAL CAPACITORS FOR THE CRYSTAL OSCILLATOR • LOW HARMONIC DISTORTION • HIGH BAND TONES PRE-EMPHASIS The M751 can provide all tone frequency pairs required for the Touch Tone Dialling System. The output :frequencies are obtained from an internal crystal controlled oscillator whose frequency is reduced in two ,independent programmable counters. The dividing ratio is controlled by the selected key.
