MAX208IDBG4

Drivers, Receivers, Transceivers Overview

The MAX208IDBG4 is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 5-V supply and includes internal charge pumps to generate the necessary voltages for RS-232 communication without requiring external inductors. The device features four drivers and four receivers, providing full duplex or half duplex operation. It incorporates ±15-kV ESD protection on all RS-232 lines, enhancing reliability in harsh environments. The component is housed in a 24-pin SSOP package and is rated for an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 24-SSOP package. Check for RoHS compliance status if required by specific regulatory standards. Confirm availability through authorized distributors to avoid counterfeit components.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple RS-232 channels powered by a single 5-V rail. It is suitable for applications demanding high ESD immunity without additional protective circuitry. Consider the thermal performance within the industrial temperature range during layout. Verify signal integrity requirements against the specified data rate capabilities.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX208 family of multichannel RS-232 transceivers. It shares functional similarities with other devices in the series but differs in package configuration and specific electrical characteristics. The IDBG4 suffix indicates a specific tape-and-reel packaging option and lead-free composition. It serves as a direct replacement for older versions with minor packaging updates.

Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives such as the MAX208CDBR or MAX208IDR. Verify that substitute parts maintain the same ESD protection levels and operating voltage ranges. Ensure that any replacement supports the required data rates and channel configurations.
