MT8888CE1

MT8888CE1 Description

The MT8888CE1 is a DTMF (Dual-Tone Multi-Frequency) transceiver integrated circuit (IC) designed for telecommunication applications. Manufactured by Microchip Technology, this obsolete component is housed in a through-hole mounted tube package, specifically a 20DIP (Dual In-line Package). The MT8888CE1 operates within a supply voltage range of 4.75V to 5.25V and draws a supply current of 7mA. It is classified under the ECCN (Export Control Classification Number) EAR99 and is compliant with REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) regulations, as well as ROHS3 (Restriction of Hazardous Substances) standards. The moisture sensitivity level (MSL) is rated at 1 (Unlimited), indicating it is not sensitive to moisture and can be stored without special precautions.

MT8888CE1 Features

• DTMF Transceiver Functionality: The MT8888CE1 is specifically designed to handle DTMF signaling, making it ideal for applications requiring tone generation and detection in telecommunication systems.
• Low Supply Current: With a supply current of only 7mA, this IC is energy-efficient, making it suitable for systems where power consumption is a critical consideration.
• Wide Supply Voltage Range: The ability to operate within a supply voltage range of 4.75V to 5.25V provides flexibility in power supply design and ensures compatibility with various power sources.
• Through Hole Mounting: The through-hole mounting type ensures robust mechanical stability and ease of integration into printed circuit boards (PCBs), particularly in industrial and commercial applications.
• Compliance and Safety: The MT8888CE1 is REACH unaffected and ROHS3 compliant, ensuring it meets environmental and safety standards, which is crucial for compliance with global regulations.
• Moisture Sensitivity Level 1: The MSL rating of 1 (Unlimited) means the component can be stored and handled without the need for moisture-sensitive precautions, simplifying inventory management and reducing the risk of moisture-related damage.

MT8888CE1 Applications

The MT8888CE1 is particularly well-suited for applications in the telecommunications industry where DTMF signaling is a fundamental requirement. Some specific use cases include:

• Telephony Systems: Ideal for use in telephone systems, PBX (Private Branch Exchange) equipment, and other telecommunication devices that require DTMF tone generation and detection.
• Telecom Infrastructure: Suitable for integration into telecom infrastructure components such as modems, fax machines, and other communication devices.
• Industrial Automation: Can be used in industrial automation systems where DTMF signaling is necessary for remote control and monitoring applications.
• Security Systems: Applicable in security systems that utilize DTMF signaling for access control, alarm systems, and other security-related functions.

Conclusion of MT8888CE1

The MT8888CE1, despite being an obsolete product, remains a reliable and efficient DTMF transceiver IC. Its low supply current, wide supply voltage range, and robust through-hole mounting make it a versatile component for various telecommunication applications. Compliance with REACH and ROHS3 standards ensures it meets environmental and safety requirements, while its moisture sensitivity level of 1 simplifies storage and handling. Although it is no longer in production, the MT8888CE1 continues to be a valuable component for legacy systems and specific applications where its unique features and performance benefits are required.
