Description:

Dtmf dialer for binary data-in.

S5T0167, DTMF DIALER FOR BINARY DATA-IN

Pin No 1 2 Symbol VDD TEN Positive supply input Tone enable input.

An internal pull-up resistor is in a chip.

When this pin connects to 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 D0 ~

S5T0167 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 Operati
