The KT3170 is a complete Dual Tone Multiple Frequency (DTMF) receiver fabricated using low-power CMOS and Switched-Capacitor Filter technology. This LSI separates tones using band-split filters and a counting section to verify frequency and duration before outputting a 4-bit digital code. It detects all 16 standard DTMF tones.
Key features include low power consumption of 15mW typical and a single 5V power supply. It utilizes an inexpensive 3.58MHz crystal for its on-chip clock generator, minimizing external components. The device offers three-state outputs for microprocessor interfacing and a power-down mode.
Applications for the KT3170 include PABX systems, Central Offices, Paging Systems, Remote Control, Credit Card Systems, Key Phone Systems, Answering Phones, Home Automation, Mobile Radio, and Remote Data Entry. The KT3170N is available in an 18-DIP-300A package and operates from -25°C to +75°C.
