MAX3362AKA#G16

Overview

The MAX3362AKA#G16 is a low-power, high-speed RS-485/RS-422 transceiver operating from a single +3.3V supply. It supports data rates up to 20Mbps with driver and receiver propagation delays below 50ns and output skew under 6ns. The device features a 1/8-unit-load receiver input impedance (96kΩ), allowing up to 256 transceivers on the bus. Operating current is 1.7mA, reducing to 1µA in shutdown mode. It includes hot-swap capability, short-circuit current limiting, and thermal shutdown protection. The component is housed in an 8-pin SOT23 package and operates within an automotive temperature range of -40°C to +125°C.

Feature Summary

• Hot-swap feature eliminates false transitions during circuit initialization
• Half-duplex operation with independent driver and receiver enable controls
• Integrated protection against excessive power dissipation via thermal shutdown
• Interoperable with +5V logic levels despite 3.3V operation

Applications

• Multidrop clock and data distribution
• Telecom equipment
• Industrial controls

Procurement Notes

Verify the specific suffix matches the required temperature grade and RoHS compliance status. Confirm the package code corresponds to the 8-pin SOT23 form factor. Ensure the ordering information aligns with the intended application environment specifications.

Selection Notes

Select this component for applications requiring robust multidrop communication with minimal power consumption. The wide common-mode range and high node capacity make it suitable for electrically noisy industrial environments. Verify that the 20Mbps speed meets the system timing requirements.

Part Context

This part belongs to the MAX3362 family of half-duplex transceivers designed for RS-485 and RS-422 standards. The 'A' designation indicates the extended automotive temperature range variant. The '#G16' suffix typically denotes specific packaging or tape-and-reel configurations compliant with industry standards.

Replacement Considerations

Direct substitutes include other MAX3362 variants such as MAX3362EKA for commercial temperature ranges. Cross-compatibility exists with standard RS-485 transceivers sharing the same pinout and electrical characteristics.

FAQ

How does the hot-swap feature function?

An internal pulldown circuit holds the Driver Enable (DE) pin low for at least 10µs upon power-up, preventing false driver activation caused by leakage currents or parasitic capacitance during board insertion.

What is the maximum number of devices supported on the bus?

Due to its 1/8-unit-load receiver input impedance, the MAX3362 allows up to 256 transceivers to be connected simultaneously on a single communication line.

How is the low-power shutdown mode activated?

Shutdown mode is entered by driving the Receiver Enable (RE) pin high and the Driver Enable (DE) pin low simultaneously for at least 600ns.
