MAX3362AKA+T

Overview

The MAX3362AKA+T is a low-power, high-speed half-duplex transceiver for RS-485/RS-422 communication. It operates from a single +3.3V supply (3.135V to 3.465V) and supports data rates up to 20Mbps with driver/receiver propagation delays below 50ns and output skew under 6ns. The device features a 1/8-unit-load receiver input impedance, allowing up to 256 units on the bus. Operating supply current is typically 1.7mA, reducing to 1μA in shutdown mode. It includes hot-swap capability, short-circuit current limiting, and thermal shutdown protection. The component is specified over an industrial temperature range of -40°C to +125°C and is housed in an 8-pin SOT package.

Feature Summary

• Hot-swap feature prevents false transitions during circuit initialization
• Low-power shutdown mode reduces supply current to 1μA
• 1/8-unit-load receiver input impedance supports up to 256 transceivers on the bus
• Integrated thermal shutdown and short-circuit current limiting

Applications

• Multidrop clock/data distribution applications
• Telecom equipment
• Security equipment
• Point-of-sale equipment
• Industrial controls

Procurement Notes

Verify the specific suffix 'AKA' confirms the -40°C to +125°C automotive temperature range variant. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the ordering information matches the exact manufacturer product number to avoid discrepancies in electrical characteristics or package type.

Selection Notes

Select this part when a single +3.3V supply is required for RS-485/RS-422 networks. The wide operating temperature range (-40°C to +125°C) makes it suitable for harsh environments. Consider the 1/8-unit-load impedance if high node counts are needed. Verify that the 20Mbps data rate meets system requirements.

Part Context

The MAX3362 series includes variants like the MAX3362EKA+T, which shares the same electrical specifications but is rated for the extended temperature range of -40°C to +85°C. The 'A' suffix specifically denotes the wider automotive-grade temperature capability. Both variants utilize the same 8-pin SOT package and BiCMOS process technology.

Replacement Considerations
