MAX202IDWR

Drivers, Receivers, Transceivers Overview

The MAX202IDWR is a dual RS-232 transceiver manufactured by Texas Instruments, designed for asynchronous communication controllers. It integrates two line drivers and two line receivers with an internal charge pump circuit that converts a single +5V supply to ±10V levels, eliminating the need for external negative voltage sources. The device supports data rates up to 120 kb/s and operates within a supply voltage range of 4.5V to 5.5V. It features ±15-kV ESD protection on all pins, including ground, ensuring robust performance in industrial environments. Packaged in a 16-pin SOIC (DW) format with a reel packaging style, it draws 15 mA of operating current and functions across a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IDWR' corresponds to the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations prior to integration into final assemblies.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring dual-channel RS-232 connectivity without external negative voltage generation. Ensure the application environment remains within the specified -40°C to +85°C operational range. Verify that the 120 kb/s maximum data rate meets the system's throughput requirements and that the 16-pin SOIC footprint aligns with the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202 family of low-power RS-232 transceivers. It shares functional similarities with the MAX232 but utilizes smaller external capacitors due to optimized internal charge pump design. The 'I' designation indicates industrial temperature rating, while 'W' denotes the SOIC package type, and 'R' specifies reel packaging for automated surface-mount assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

MAX202IDW serves as the tube-packaged equivalent. MAX202IDR offers identical electrical specifications with cut-tape packaging options.
