MAX3232EIDB

Overview

The MAX3232EIDB is a Texas Instruments RS-232 transceiver in a 16-pin SSOP package. It operates on a single 3V to 5.5V supply and supports data rates up to 250kbit/s. The device integrates two drivers and two receivers with ±15kV IEC ESD protection. Typical standby current is 300μA, requiring four 0.1μF external capacitors.

Feature Summary

• Automotive qualified for industrial PCs and wired networking
• Dual charge pump circuit enables operation from a single low-voltage supply
• Integrated ±15kV IEC electrostatic discharge protection on serial port pins

Applications

• Industrial PCs
• Wired networking
• Data center and enterprise computing
• Battery-powered systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement to ensure compatibility with assembly processes.

Selection Notes

Select this component when an automotive-grade RS-232 interface with robust ESD protection is required. Ensure the design accommodates the necessary external capacitor values for the charge pump circuit. Verify that the operating voltage range aligns with the system power supply specifications.

Part Context

This part belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. It provides electrical interfacing between asynchronous communication controllers and serial-port connectors while meeting TIA/EIA-232-F standards.

Replacement Considerations
