MAX232ECDR

Overview

The MAX232ECDR 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 full-duplex communication at data rates up to 120 kb/s. It features an industrial temperature range from -40°C to +85°C and draws a maximum supply current of 10 mA. Packaged in a 16-pin SOIC surface-mount format, it integrates charge pumps for internal voltage generation.

Feature Summary

• Integrates dual drivers and receivers for complete RS-232 signal conversion
• Includes on-chip charge pumps eliminating the need for external positive/negative voltage sources
• Provides ESD protection capabilities for enhanced signal integrity

Applications

• Industrial control systems requiring serial communication
• Point-of-sale terminals and barcode scanners
• Medical equipment with serial interface requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may vary. Ensure the specific suffix matches required packaging and temperature grades before finalizing orders.

Selection Notes

Select this component when a dual-channel RS-232 solution is needed for 5V logic systems. Compare against the MAX3232 series if lower power consumption or 3.3V operation is required. Verify that the 120 kb/s speed meets application timing constraints.

Part Context

This part belongs to the MAX232 family of RS-232 transceivers. It shares functional similarities with variants like the MAX232IDR but differs in temperature rating and package type. The 'E' suffix typically denotes extended industrial temperature specifications compared to commercial grade parts.

Replacement Considerations

The MAX232IDR serves as a pin-compatible alternative with similar electrical characteristics. Other compatible options include the MAX232ESE+ from Maxim Integrated. Verify pinout compatibility and voltage levels before substitution.
