MAX33048EASA+

Overview

The MAX33048EASA+ is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 20 Mb/s. The device features 40 kV ESD protection on the bus pins, ensuring robust performance in harsh environments. It includes one driver and one receiver housed in an SOIC-8 package. The operational temperature range spans from -40°C to +125°C, with a typical quiescent current of 6 mA.

Feature Summary

• Provides full-duplex communication capabilities for RS-422 and RS-485 networks.
• Integrates high-level electrostatic discharge protection rated at 40 kV on the bus lines.
• Operates reliably across an extended industrial temperature range without requiring shutdown control.

Applications

• Industrial automation systems requiring robust serial communication.
• Building automation and control networks.
• Metering applications in utility infrastructure.
• Process control instrumentation.

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference manufacturer part numbers to avoid counterfeit components. Confirm availability status through authorized distributors as supply constraints may affect procurement timelines.

Selection Notes

Select this component when full-duplex operation is required for simultaneous transmission and reception. The 40 kV ESD rating makes it suitable for environments with significant static discharge risks. Compare against half-duplex alternatives like the MAX33045 if bidirectional single-wire communication suffices. Verify that the 20 Mb/s speed meets the network latency requirements.

Part Context

This device belongs to the MAX3304x series of high-speed transceivers designed for reliable data transmission in noisy industrial settings. It complements other variants such as the MAX33047 (half-duplex) and MAX33049 (low-power). The series emphasizes durability and signal integrity for critical communication links.

Replacement Considerations

The MAX33045EASA+ serves as a related half-duplex alternative within the same family. Verify functional differences regarding duplex mode and pinout compatibility before substitution. No direct public substitute part numbers are confirmed for identical full-duplex specifications.
