KT3170 Description

Short technical summary and product information.

The KT3170 is a complete Dual Tone Multiple Frequency (DTMF) receiver fabricated using low power CMOS and Switched-Capacitor Filter technology. This LSI integrates band split filters and a counting section to verify received tones, decoding all 16 DTMF tone pairs into a 4-bit digital code.

 

Key features include low power consumption of 15mW typical and a single 5V power supply. It utilizes an inexpensive 3.58MHz crystal for its clock generator and offers three-state outputs for microprocessor interfacing. The device operates within a temperature range of -25°C to +75°C and is available in an 18-DIP-300A package.

 

Applications for the KT3170 include PABX systems, Central Offices, Paging Systems, Remote Control, Credit Card Systems, Key Phone Systems, Answering Phones, Home Automation Systems, Mobile Radios, and Remote Data Entry. Its design minimizes externally required components, making integration simpler.
