MAX3237ECPWRG4

Overview

The MAX3237ECPWRG4 is a single-channel RS-232 transceiver manufactured by Texas Instruments, designed for operation with supply voltages ranging from 3 V to 5.5 V. It integrates five drivers and three receivers within a 28-pin TSSOP package, supporting full-duplex communication at data rates up to 1 Mb/s. The device complies with EIA/TIA-232-F and V.28 standards, featuring Schmitt trigger inputs for noise immunity. It operates within a commercial temperature range of 0°C to +70°C and draws a typical operating supply current of 2 mA.

Feature Summary

• Integrates five line drivers and three receivers in a single compact package
• Operates directly from a single 3-V to 5.5-V power supply
• Supports data transmission rates up to 1 Mb/s
• Includes Schmitt-trigger inputs to enhance noise rejection

Applications

• Industrial control systems requiring serial communication
• Portable battery-powered equipment utilizing low-voltage logic
• Modems and fax machines adhering to RS-232 standards
• Point-of-sale terminals and barcode scanners

Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free and RoHS compliance status. Ensure the TSSOP-28 package variant matches the design footprint requirements. Confirm the 'E' grade designation aligns with the necessary commercial temperature range specifications for the target application environment.

Selection Notes

Select this component when a single-supply RS-232 interface is required with multiple transmit and receive channels. It is suitable for designs constrained by space due to its TSSOP packaging. Consider the 1 Mb/s speed limit and 2 mA quiescent current when evaluating performance against higher-speed or lower-power alternatives.

Part Context

This device belongs to the MAX3237 family of multichannel RS-232 line drivers and receivers. It shares functional similarities with other single-supply transceivers but distinguishes itself through the specific count of five drivers and three receivers. The G4 suffix indicates environmental compliance features consistent with Texas Instruments' product labeling conventions.

Replacement Considerations

The MAX3237ECDWG4 is a documented alternative offering identical electrical characteristics in an SOIC-28 package. Verify pin compatibility and thermal performance differences between the TSSOP and SOIC footprints before substitution.
