Overview
The MAX3232EIDWG4 is an automotive-qualified, dual RS-232 transceiver from Texas Instruments. It operates on a single 3V to 5.5V supply and supports data rates up to 250kbit/s with a maximum slew rate of 30V/μs. The device integrates two drivers and two receivers within a 16-pin TSSOP (PW) package measuring 5mm x 6.4mm. It features ±15kV IEC ESD protection and requires four external 0.1μF capacitors for the charge pump circuit. Operating temperatures range from -40°C to +85°C, with a typical standby current of 300μA.
Feature Summary
- Automotive qualification meeting AEC-Q100 standards
- Integrated dual charge-pump circuit for single-supply operation
- Robust ±15kV IEC electrostatic discharge protection
- Compatible with 5V logic inputs when powered by 3.3V
Applications
- Industrial PCs
- Wired networking equipment
- Data center and enterprise computing systems
- Battery-powered portable devices
Procurement Notes
Verify the specific ordering suffix against the latest TI Package Option Addendum to confirm the exact package type and material finish. Confirm that the component meets the required automotive reliability standards for your specific application environment before finalizing procurement.
Selection Notes
Select this component for designs requiring automotive-grade RS-232 interfaces with high ESD tolerance. Ensure the design accommodates the required four external capacitors for the internal charge pump. Verify that the 250kbit/s signaling rate aligns with the system's communication requirements.
Part Context
This part belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. It serves as a specialized automotive variant designed for harsh environments, offering enhanced reliability compared to standard commercial versions while maintaining pin compatibility with other industry-standard transceivers.
Replacement Considerations
The SNx5C3232 is identified as a pin-compatible alternative offering higher speed capabilities. Catalog versions such as the MAX3232E may be considered if automotive qualification is not strictly required.
