LC73881M
DTMF Receiver LSI
Applications
• Remote controllers for telephone answering machines
and other telephone products
Features
• Detects 16 DTMF signals.
• Includes on-chip all filters required in a DTMF receiver
— Dial-tone filter
— High-frequency group bandpass filter
— Low-frequency group bandpass filter
• Serial data output
• Supports microprocessor-controlled guard times.
• Wide operating power-supply voltage range: 2.7 to 5.5 V
• Supports a low power mode that allows current
dissipation to be reduced.
