Overview
The MAX3238IDB is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates on a single 3-V to 5.5-V power supply and features five drivers and three receivers. The device supports data rates up to 250 kbps and includes +/-15-kV ESD protection on all inputs and outputs. It is housed in a 28-pin SSOP package and functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates five independent drivers and three receivers for comprehensive serial communication connectivity.
- Provides robust electrostatic discharge protection rated at +/-15 kV according to Human Body Model standards.
- Operates efficiently from a single low-voltage power supply ranging from 3 V to 5.5 V.
Applications
- Industrial control systems requiring reliable serial communication interfaces
- Portable equipment utilizing battery-powered single-supply operation
- Modems and fax machines needing high ESD tolerance
Procurement Notes
Verify the specific suffix 'DB' corresponds to the 28-pin SSOP package configuration when sourcing. Confirm that the component meets RoHS compliance requirements if restricted substances are prohibited in the assembly process. Ensure the operating environment remains within the specified -40°C to +85°C temperature limits for optimal performance.
Selection Notes
Select this component when a design requires multiple RS-232 channels beyond standard dual-driver configurations. It serves as a suitable alternative to the MAX3232 series for applications demanding higher channel density. Consider the 28-pin SSOP footprint constraints during PCB layout planning to ensure adequate spacing for the required external capacitors.
Part Context
This part belongs to the MAX3238 family of multichannel RS-232 transceivers. It shares functional similarities with the MAX3237 and MAX3243 but offers a distinct combination of five drivers and three receivers. The IDB suffix indicates the industrial temperature grade and specific surface-mount packaging variant.
Replacement Considerations
The MAX3238EIPWR is a pin-compatible alternative available in a TSSOP-28 package. Designers must verify mechanical footprint differences between SSOP and TSSOP styles before substitution. Electrical characteristics remain consistent across these package variations within the same family.
