KS58015 Datasheet (Samsung) - DTMF DIALER FOR BINARY DATA-IN

KS58015, DTMF DIALER FOR BINARY DATA-IN

Pin No 1 Symbol VDD TEN Positive supply input Tone enable input.

An internal pull-up resistor is in a chip.

When this pin connects to 2 logic ‘ low’ , the oscillator is inhibited and the tone generators and output transistor are turned off.

A low to high transition on this pin latches in data from D
