MAX3237ECPW

Overview

The MAX3237ECPW is a single-channel RS-232 line driver and receiver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbit/s. The device is housed in a 28-pin TSSOP package and functions across an operating temperature range of 0°C to 70°C. It integrates five drivers and three receivers for full-duplex communication, complying with EIA/TIA-232-F standards.

Feature Summary

• Integrates five independent drivers and three receivers for comprehensive serial communication
• Provides high electrostatic discharge protection rated at 15 kV on all RS-232 lines
• Features low power consumption with shutdown mode reducing supply current to below 1 µA

Applications

• Industrial control systems requiring robust serial connectivity
• Portable battery-powered equipment utilizing 3-V or 5-V supplies
• Modems and portable instruments needing ESD-protected interfaces

Procurement Notes

Verify the specific suffix 'CPW' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering number with authorized distributors to confirm availability and authenticity before purchase.

Selection Notes

Select this component when a single-channel RS-232 interface is sufficient for the design. It is suitable for applications requiring high-speed data transmission up to 1 Mbit/s. Consider the 28-pin TSSOP footprint for space-constrained PCB layouts. Verify that the 0°C to 70°C commercial temperature range aligns with the operational environment.

Part Context

This part belongs to the MAX3237E family of True RS-232 transceivers from Texas Instruments. The series is designed for low-power, single-supply operation. Other variants in the family may offer different channel counts or extended temperature ranges. The MAX3237ECPW specifically denotes the commercial grade version in the specified package.

Replacement Considerations

Direct substitutes include other MAX3237E variants with compatible pinouts. Check for equivalent packages such as SOIC-28 if lead-free processing is required. Ensure any replacement maintains the 1-Mbit/s speed and 15-kV ESD protection levels.
