MAX232IDWG4

Overview

The MAX232IDWG4 is a dual driver and receiver RS-232 transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V, typically utilizing a single 5 V source. The device supports data rates up to 120 kb/s with full-duplex communication capabilities. It features two drivers and two receivers housed in a 16-pin SOIC package. The component functions across an industrial temperature range from -40°C to +85°C and includes internal charge pump circuitry for voltage generation.

Feature Summary

• Integrates dual EIA-232 drivers and receivers for complete serial communication interface functionality
• Utilizes internal charge pump technology to generate required RS-232 voltage levels from a single power supply
• Provides robust signal transmission with specified propagation delay characteristics

Applications

• Industrial control systems requiring RS-232 connectivity
• Embedded devices needing serial port expansion
• Communication modules interfacing microcontrollers with standard RS-232 peripherals

Procurement Notes

Verify the specific suffix 'DWG4' against official Texas Instruments documentation to confirm the wide-body SOIC package and lead-free composition. Confirm current lifecycle status as end-of-life products may have limited availability or require alternative sourcing strategies. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with a 5 V supply. Compare against the MAX232E series if higher data rates or enhanced ESD protection are necessary. Verify that the 120 kb/s speed meets application requirements. Consider package constraints and thermal performance within the -40°C to +85°C operating range.

Part Context

This part belongs to the MAX232 family of RS-232 transceivers from Texas Instruments. It shares core functionality with variants like the MAX232ID and MAX232IDR but differs in packaging and manufacturing specifications. The 'DWG4' designation indicates a specific tape-and-reel or tube configuration and compliance attributes defined by the manufacturer.

Replacement Considerations

The MAX232EIDWG4 offers similar functionality with improved ESD protection and higher data rates. The MAX232IDR serves as a pin-compatible alternative in a standard SOIC package. Verify electrical parameters and package dimensions before substitution.
