MAX3467EPA+

Drivers, Receivers, Transceivers Overview

The MAX3467EPA+ is a full-duplex RS-485/RS-422 transceiver operating from a single +5V supply. It features true fail-safe circuitry guaranteeing a logic-high receiver output when inputs are open or shorted. The device supports data rates up to 40Mbps with driver propagation delays under 15ns and receiver delays under 20ns. It includes thermal shutdown and current limiting for overload protection. The component is housed in an 8-pin PDIP package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• True fail-safe receiver ensures a logic-high output during bus idle or fault conditions
• Supports multipoint transmission with 1/4-unit-load input impedance allowing up to 128 devices on the bus
• Integrated thermal-shutdown and foldback current-limiting protect against excessive power dissipation

Drivers, Receivers, Transceivers Applications

• High-speed RS-485 communications
• High-speed RS-422 communications
• Profibus applications
• Industrial-control local area networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix matches the required specifications. The plus sign indicates lead-free and RoHS compliance. Confirm the 'E' suffix corresponds to the extended industrial temperature range of -40°C to +85°C. Ensure the 'PA' designation aligns with the plastic DIP package requirements for your specific board layout.

Drivers, Receivers, Transceivers Selection Notes

Select this part for full-duplex applications requiring independent transmit and receive paths. Unlike half-duplex variants, it utilizes separate enable pins for the driver and receiver. Verify that the system requires a dedicated shutdown pin (SHDN) as this specific model lacks internal combined enable logic found in other family members.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX3465–MAX3469 family of high-speed differential bus transceivers. While sharing core electrical characteristics like the 40Mbps rate and fail-safe design, the MAX3467 is distinct as a full-duplex device with eight pins. It differs from the half-duplex MAX3468/MAX3469 and the hot-swap capable MAX3465/MAX3466.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes within the same package include the MAX3467CPA for commercial temperature ranges. For half-duplex implementations, the MAX3468EPA or MAX3469EPA may be considered if the application allows for shared driver/receive lines.
