MAX3232CDG4

Overview

The MAX3232CDG4 is a dual RS-232 transceiver manufactured by Texas Instruments, designed for communication applications requiring reliable data transmission. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features two drivers and two receivers, enabling full-duplex communication. Packaged in an SSOP-16 format, it is rated for operation between 0°C and +70°C. Key electrical specifications include a maximum operating current of 1 mA and ESD protection capabilities of 15 kV, ensuring robust performance in standard industrial environments.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external voltage sources
• Provides true RS-232 signal levels compatible with standard interface protocols
• Offers high electromagnetic interference immunity for stable data integrity

Applications

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

Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's official documentation to confirm lead-free compliance and RoHS status. Ensure the package type matches the SSOP-16 specification required for the target PCB layout. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a dual-channel RS-232 solution is needed for 3V to 5.5V logic systems. It is suitable for applications prioritizing low power consumption and moderate data speeds. Consider alternative packages if higher temperature ranges or different form factors are required for the specific enclosure constraints.

Part Context

This part belongs to the MAX3232 family of multichannel RS-232 transceivers from Texas Instruments. The family includes variants with different channel counts and package options. The MAX3232 specifically provides two channels, distinguishing it from single-channel or quad-channel counterparts within the same product line.

Replacement Considerations

Direct substitutes include the MAX3232IDWR and MAX3232CDBR. Verify that the replacement variant maintains the same SSOP-16 footprint and meets the required operating temperature range for the application.
