MAX232IDWRG4

Overview

The MAX232IDWRG4 is a dual EIA-232 driver and receiver integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. The device supports data rates up to 120 kb/s and provides full-duplex communication capabilities. It features two drivers and two receivers housed in a 16-pin SOIC package. The component functions reliably across an extended temperature range from -40°C to +85°C and draws approximately 10 mA of operating current.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 signal conversion
• Utilizes internal charge pump circuitry to generate required voltage levels from a single 5-V supply
• Provides ESD protection for enhanced reliability in industrial environments

Applications

• RS-232 serial communication interfaces in embedded systems
• Modem control circuits requiring dual channel transmission
• Industrial equipment utilizing standard EIA-232 protocols

Procurement Notes

Verify the specific suffix 'WRG4' against official Texas Instruments documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel RS-232 transceiver is required in a surface-mount SOIC package. It is suitable for designs needing full-duplex communication at speeds up to 120 kb/s. Verify that the system power supply remains stable between 4.5 V and 5.5 V. Confirm that the operating environment falls within the specified -40°C to +85°C temperature range for optimal performance.

Part Context

This part belongs to the MAX232 family of interface ICs, which are widely used for converting TTL/CMOS logic levels to RS-232 voltages. The 'I' designation indicates an industrial temperature grade, while 'DWR' specifies the wide-body SOIC package and tape-and-reel shipping format. The 'RG4' suffix typically denotes lead-free construction and RoHS compliance according to Texas Instruments naming conventions.

Replacement Considerations

MAX232IDR: Same functional specifications but in cut-tape or reel packaging without the wide-body variant distinction.
