MT88L85ANR1

Telecom Overview

The MT88L85ANR1 is a single-channel DTMF transceiver integrated circuit manufactured by Microchip Technology. It operates within a supply voltage range of 2.7V to 3.6V and draws a typical operating supply current of 3.1mA. The component is designed for commercial temperature operation, functioning reliably between -40°C and +85°C. It is housed in a 24-SSOP package with a width of 5.30mm (0.209 inches), suitable for surface-mount assembly.

Telecom Feature Summary

• Integrates dual-tone multi-frequency generation and detection capabilities into a single channel
• Includes power-down mode functionality to reduce operational energy consumption
• Features an adaptive microprocessor interface for flexible system integration

Telecom Applications

• Telecommunications equipment requiring DTMF signaling
• Voice response systems and interactive voice response units
• Consumer electronics utilizing touch-tone dialing interfaces

Telecom Procurement Notes

Verify the specific suffix 'NR1' corresponds to the tape-and-reel packaging format required for automated surface-mount production lines. Confirm that the 24-SSOP footprint matches the target PCB design constraints. Ensure compatibility with the intended 2.7V to 3.6V logic levels and check for any specific handling requirements associated with the SSOP package type during assembly.

Telecom Selection Notes

Select this component when a combined DTMF transmitter and receiver solution is needed for a single channel. It is appropriate for designs prioritizing low power consumption through available power-down modes. Consider the 24-SSOP package dimensions if space efficiency is critical compared to larger DIP packages. Verify that the operating temperature range meets the environmental specifications of the final application.

Telecom Part Context

This device belongs to the family of DTMF transceivers produced by Microchip Technology, formerly Zarlink Semiconductor. These components are specialized for processing dual-tone multi-frequency signals used in telephony. The MT88L85 series provides integrated signal processing for both audio input and output paths, simplifying the design of communication interfaces.
