MAX488ESA-T

Drivers, Receivers, Transceivers Overview

The MAX488ESA-T is a low-power, half-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a single 5 V supply and supports data rates up to 250 kb/s. The device features slew-rate limiting on the driver output to minimize electromagnetic interference (EMI) during signal transitions. It includes integrated protection against electrostatic discharge (ESD), rated at 15 kV according to Human Body Model standards. The component is housed in an 8-pin SOIC package and is designed for industrial applications within an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited driver output reduces high-frequency ringing and EMI emissions.
• Integrated 15 kV ESD protection enhances reliability in harsh environments.
• Low quiescent current consumption supports battery-powered or power-sensitive designs.

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation and security networks
• Multi-drop communication buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the supplier provides traceability for the Analog Devices / Maxim Integrated origin. Cross-reference the full part number to distinguish from non-tape variants.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex RS-485 applications requiring moderate speed and low power. The 250 kb/s rate suits most industrial sensor networks. Verify that the 5 V supply voltage aligns with the system design. Consider the SOIC-8 package constraints for PCB layout. Ensure ESD requirements do not exceed the 15 kV HBM rating.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX488 family of RS-422/RS-485 transceivers. The family emphasizes low power consumption and robust ESD protection. The MAX488 variant specifically targets cost-sensitive applications where 250 kb/s bandwidth is sufficient. It shares pinouts with similar industry-standard transceivers but offers distinct ESD performance characteristics.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 5 V, 250 kb/s RS-485 transceivers in SOIC-8 packages. Verify compatibility regarding driver enable logic and receiver threshold levels. Check if alternative parts offer higher ESD ratings or different packaging options like TSSOP.
