MAX208IDB

Drivers, Receivers, Transceivers Overview

The MAX208IDB is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates with a single 5-V power supply and includes four drivers and four receivers for full-duplex communication. The device supports data rates up to 120 kb/s and features ±15-kV electrostatic discharge (ESD) protection on all RS-232 lines. It utilizes small external capacitors, typically 0.1 µF, for charge pump operation. The component is housed in a 24-pin SSOP package and is designed for industrial temperature ranges.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables operation from a single 5-V supply without requiring dual voltage sources.
• Provides robust ±15-kV ESD protection on all RS-232 transceiver lines to safeguard connected equipment.
• Supports high-speed data transmission with a guaranteed rate of 120 kb/s for reliable serial communication.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DB' corresponds to the 24-SSOP package variant when sourcing. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolescence notices or lifecycle changes directly from Texas Instruments documentation before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 4-driver/4-receiver configuration is required within a compact surface-mount footprint. Ensure the design accommodates the necessary 0.1 µF external capacitors for the internal charge pumps. Verify that the 120 kb/s speed meets the system's baud rate requirements.

Drivers, Receivers, Transceivers Part Context

The MAX208 belongs to the broader family of 5-V multichannel RS-232 transceivers from Texas Instruments. It shares functional similarities with the MAX211 and TRS208 series but offers a specific pin count and channel density suited for applications needing multiple serial ports in a limited board space.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS208IDBR is listed as a manufacturer-recommended replacement. Other potential substitutes include the MAX211 series or HIN208EIAZ, provided pin compatibility and electrical specifications align with the original design constraints.
