MAX232IDG4

Overview

The MAX232IDG4 is a dual driver/receiver RS-232 transceiver 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 features full-duplex communication. It includes two drivers and two receivers housed in a 16-pin SOIC-Narrow package. The component functions reliably across an extended temperature range from -40°C to +85°C. It draws approximately 10 mA of operating current and incorporates ESD protection mechanisms.

Feature Summary

• Integrates dual EIA-232 drivers and receivers for complete serial communication functionality
• Utilizes internal charge pump circuitry to generate required positive and negative voltages from a single 5-V supply
• Provides robust signal integrity through built-in ESD protection features

Applications

• RS-232 serial communication interfaces in industrial control systems
• Modem connections and peripheral interfacing in embedded devices
• Data transmission links between microcontrollers and PC serial ports

Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance details. Confirm availability status as the component may be subject to end-of-life notices or production changes. Ensure the SOIC-16 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a standard 5-V RS-232 interface is required with dual channel capability. It is suitable for designs needing full-duplex communication without external voltage generation components. Consider the industrial temperature range if the application environment exceeds commercial limits. Verify that the 120 kb/s data rate meets the system's throughput requirements.

Part Context

This part belongs to the MAX232 family of RS-232 transceivers from Texas Instruments. It shares core functional specifications with variants like MAX232IDR but differs in packaging and manufacturing process codes. The 'I' designation indicates the industrial temperature grade, while 'DG4' specifies the narrow SOIC package and lead-free construction.

Replacement Considerations

MAX232IDR is a pin-compatible alternative within the same family offering similar electrical characteristics in a tape-and-reel format.
