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.
14−DIP−300
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

PIN DESCRIPTION
Pin No Symbol
Descriptions
1 VDD Positive supply input
2 TEN 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 ~ D3, and tone generation
continues until this pin is connected low again.
3 ST Single tone enable. An internal pull-up resistor is in a chip.
When this pin connects to logic low, the device is in a single tone mode.
For normal operation, connects this pin to VDD or open-circuit.
4 GS Group selection input. This pin is used to select the high group or low group frequency,
when the device is in single tone mode. An internal pull-up resistor is in a chip. When this
pin connects to VDD or open, the high group will be generated, and when connects to VSS,
the low group will be generated.
5 VSS Negative supply input
6 OSC IN Oscillator input
7 OSC OUT Oscillator output
8 MUTE N-channel open drain output.
This pin is a logic high state, when the tone enable pin is a high state.
This pin goes a logic low state, when the tone enable pin is a low state.
9, 10, D0, D1, DATA-INPUTS. These are the inputs for binary-coded data, which is latched in on the
11, 12 D2, D3 rising edge of the tone enable signal.
13 N.C No connection.
14 Tone out This output is the open emitter of a NPN transistor. When an external load resistor is
connected from this pin to VSS, the tone generates on the tone enable pin = High.
