DTMF DIALER FOR BINARY DATA-IN
INTRODUCTION
The S5T0167 is a DTMF dialer for 4 bit binary data input from the
microprocessor. When the tone enable input is low, the oscillator is
inhibited 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.
