TRS3243EIPW

Drivers, Receivers, Transceivers Overview

The TRS3243EIPW is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V power supply and includes three drivers and five receivers for full-duplex communication. The device integrates charge pumps to generate the required ±10-V signals from the single supply, eliminating the need for external dual supplies. It features Schmitt-trigger inputs on receivers for noise filtering and provides ±15-kV IEC ESD protection on all RS-232 lines. The component is housed in a 28-pin TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pump circuits to generate internal voltage rails from a single low-voltage supply
• Provides robust electrostatic discharge protection compliant with IEC standards on signal lines
• Incorporates Schmitt-trigger input stages on receivers to improve noise immunity
• Supports standard RS-232 signaling protocols including EIA/TIA-232-F and V.28

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication
• Medical equipment interfaces needing high ESD tolerance
• Data acquisition modules connecting to PC or peripheral devices
• Embedded systems utilizing microcontrollers with UART capabilities

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IPW' corresponds to the TSSOP-28 package and industrial temperature range during sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design. Cross-reference with official Texas Instruments distributors to validate authenticity and lot traceability.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple transmit and receive channels within a compact footprint. It is suitable for applications where space constraints prevent the use of larger packages like SOIC or PQFP. Consider the 250-kbps data rate capability against system timing requirements. Evaluate the power consumption characteristics relative to battery-operated constraints if applicable.

Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments TRS3243 family of multichannel RS-232 transceivers. It shares functional similarities with the MAX3243 series but may differ in specific electrical parameters or packaging options. The family is designed to replace older discrete solutions or simpler transceivers in complex serial bus architectures.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3243EIPW is a direct functional equivalent from Texas Instruments. Verify pin compatibility and electrical parameter alignment before substitution. Other variants such as TRS3243IPWR offer different packaging options.
