MAX14841EASA+

Drivers, Receivers, Transceivers Overview

The MAX14841EASA+ is a +3.3V half-duplex RS-485 transceiver supporting data rates up to 40Mbps in an 8-pin SO package. It operates within a supply voltage range of 3.0V to 3.6V, drawing a typical supply current of 1.5mA and a maximum shutdown current of 10µA. The device features true fail-safe receiver inputs that guarantee a logic-high output when inputs are shorted or open. It provides ±35kV HBM ESD protection on the A/B pins and includes thermal shutdown at 160°C. Operating temperatures range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• True fail-safe receiver input guarantees a logic-high output state during bus shorts or open conditions.
• Integrated hot-swap capability prevents false transitions on the bus during power-up or board insertion.
• High electrostatic discharge protection rated at ±35kV (HBM) on differential I/O pins.

Drivers, Receivers, Transceivers Applications

• Motion Controllers
• Fieldbus Networks
• Industrial Control Systems
• Backplane Buses
• HVAC Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and environmental compliance status. Confirm availability through authorized distribution channels as stock levels fluctuate. Ensure the component matches the required pinout and electrical specifications for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this component over the MAX14840E variant when a guaranteed logic-high receiver output is required during fault conditions such as open or shorted bus lines. Verify that the system operates within the specified 3.0V to 3.6V supply voltage range and requires support for data rates up to 40Mbps.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14840E/MAX14841E family of high-speed, +3.3V RS-485 transceivers designed for robust communication in noisy industrial environments. The family offers options for symmetrical or true fail-safe operation and is available in both standard 8-pin SO and compact TDFN-EP packages.

Drivers, Receivers, Transceivers Replacement Considerations

MAX14840EASA+ is a functional alternative within the same family but utilizes symmetrical fail-safe logic rather than true fail-safe behavior.

Drivers, Receivers, Transceivers FAQ

What is the receiver output state when the A and B inputs are shorted?

The MAX14841EASA+ features true fail-safe inputs that guarantee a logic-high receiver output when the differential inputs are shorted or open.

How does the device handle hot-swap events?

Internal circuitry holds the driver enable low and receiver enable high during power-up, preventing false bus transitions caused by leakage currents or parasitic capacitance during board insertion.

What is the maximum data rate supported by this transceiver?

The device supports half-duplex RS-485 communication at data rates up to 40Mbps.
