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.
