Samsung S5T0167X01-S0B0 Datasheet
DTMF DIALER FOR BINARY DATA-IN S5T0167
INTRODUCTION
14−DIP−300
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.
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
