TRS3243IPW

Drivers, Receivers, Transceivers Overview

The TRS3243IPWRG4 is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 5.5V. The device integrates three drivers and five receivers, supporting full-duplex communication compliant with EIA-232-F and TIA-232-F standards. It utilizes Schmitt trigger inputs for noise immunity. The component is housed in a 28-pin TSSOP package with dimensions of 9.7 mm length. It functions as a line transceiver with single-ended input characteristics.

Drivers, Receivers, Transceivers Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive serial communication support.
• Features Schmitt trigger inputs on the receiver side to enhance signal integrity and noise rejection.
• Supports standard RS-232 protocols including EIA-232-F and TIA-232-F specifications.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring robust serial communication interfaces.
• Data acquisition equipment utilizing RS-232 connectivity.
• Embedded systems needing reliable full-duplex data transmission.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix (e.g., G4) against the required RoHS compliance status. Confirm the package type matches the PCB footprint requirements. Ensure the operating temperature range aligns with the system environment. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Validate that the pinout configuration corresponds to the design schematic.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a multichannel RS-232 solution is required with integrated charge pumps. Consider the 28-pin TSSOP package for space-constrained designs. Evaluate the 3V to 5.5V supply range compatibility with the system power rails. Verify that the driver and receiver counts meet the interface requirements. Check for necessary ESD protection levels if exposed connectors are present.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments RS-232 interface IC family. It shares functional similarities with other MAX3243 variants but differs in packaging and compliance markings. The TRS prefix often indicates specific regional or compliance variations within the broader MAX series lineup. It serves as a direct replacement for legacy RS-232 transceivers in modern low-voltage applications.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3243EIPWR is a compatible alternative offering similar electrical characteristics. The MAX3243MPWREP provides military-grade enhancement options. Verify pin-to-pin compatibility before substitution. Ensure voltage and current specifications match the target application requirements.
