No Preview Available ! KS58015 DTMF DIALER FOR BINARY DATA-IN INTRODUCTION The KS58015 is a DTMF dialer for 4 bit binary data input from microprocessor. When the tone enable input low, the oscillator is in- hibited and the device is in a low power consumption at standby mode. On the low to high transition of tone enable, data is latched into the device and selected the standard DTMF signals. The N-channel open drain output provides a MUTE output during tone generation. 14-DIP-300 14-SOP-225B FEATURES • Direct interface with microprocessor • Generates 16 standard tones • Uses inexpensive TV crystal or ceramic resonator (3.579545MHz) • Very low total harmonic distortion • Low power standby mode • Binary data inputs with latches • Wide Operating Voltage : 2.5 ~ 8.0V BLOCK DIAGRAM VDD OSC IN OSC OUT OSC ORDERING INFORMATION Device KS58015N KS58015D Package 14-DIP-300 14-SOP-225B Operating Temperature - 30°C ~ + 70°C MUTE LOGIC MUTE TEN ST GS D0 D1 D2 D3 CONTROL CIRCUIT DAT A LATCH & DECODER ROW & COLUMN TONE COUNTER 4 D/A CONVER TER & MIXING VS S Fig.1 TONE OUT 1 page
