MAX3469CSA

Drivers, Receivers, Transceivers Overview

The MAX3469CSA+ is a half-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates at data rates up to 40 Mb/s with a single driver and receiver. The device functions on a fixed 5 V supply, drawing 2.5 mA of quiescent current. It features fail-safe circuitry and supports input voltages from 800 mV to 2 V. Key electrical parameters include a propagation delay of 15 ns to 20 ns, output voltage of 3 V, and power dissipation of 471 mW. It is housed in an SOIC-8 surface-mount package and operates within a commercial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Fail-safe receiver design ensures a high logic state when inputs are open or disconnected
• Supports high-speed data transmission up to 40 Mb/s for efficient communication
• Half-duplex operation allows bidirectional data flow over a single differential pair

Drivers, Receivers, Transceivers Applications

• Profibus network interfaces
• RS-485 multi-drop communication systems
• RS-422 point-to-point or multi-point links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status through manufacturer datasheets. Check availability as distribution channels may vary. Ensure the component matches the required interface specifications before integration into designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust RS-485/RS-422 connectivity with fail-safe protection. The SOIC-8 package suits space-constrained surface-mount designs. Verify that the 5 V operating voltage aligns with system power rails. Consider the 40 Mb/s speed limit relative to network requirements.

Drivers, Receivers, Transceivers Part Context

The MAX3469 belongs to the Maxim Integrated family of high-speed differential transceivers. It is designed for reliable communication in noisy industrial environments. The CSA variant specifically denotes the commercial temperature range and SOIC-8 packaging, distinguishing it from extended temperature or through-hole options.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3469EPA serves as a pin-compatible alternative offering through-hole PDIP-N packaging and extended temperature range capabilities. Verify functional equivalence regarding electrical parameters before substitution.
