MAX3362EKA#TG15

Overview

The MAX3362EKA#TG15 is a low-power, high-speed RS-485/RS-422 transceiver operating from a single +3.3V supply (3.135V to 3.465V). It features one differential driver and receiver with data rates up to 20Mbps. Driver and receiver propagation delays are guaranteed below 50ns, with output skew under 6ns. The device draws 1.7mA in normal operation and 1µA in shutdown mode. It supports half-duplex communication, includes hot-swap capability, and operates within an extended temperature range of -40°C to +85°C in an 8-pin SOT package.

Feature Summary

• Hot-swap feature prevents false transitions during circuit initialization
• 1/8-unit-load receiver impedance allows up to 256 transceivers on the bus
• Current limiting and thermal shutdown protect against excessive power dissipation
• Interoperable with +5V logic levels

Applications

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

Procurement Notes

Verify the specific suffix #TG15 against official manufacturer documentation to confirm exact packaging and RoHS compliance status. Confirm availability as this variant may be subject to production changes or end-of-life notices. Cross-reference the ordering information table for accurate lead times and current part status before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high-speed RS-485/RS-422 communication with low power consumption. Ensure the system voltage aligns with the +3.3V requirement. Consider the automotive temperature range variant if operating conditions exceed standard industrial limits. Verify that the 8-pin SOT package fits the available PCB space constraints.

Part Context

The MAX3362 belongs to Maxim Integrated's family of high-speed, low-power transceivers designed for multidrop networks. It complements other RS-485/RS-422 solutions by offering reduced unit load and enhanced protection features. The EKA suffix typically denotes the extended temperature range variant within this product line.

FAQ

How does the hot-swap feature function?

An internal pulldown circuit holds the DE input low for at least 10µs upon power-up, preventing false driver enable states caused by leakage currents or parasitic capacitance during board insertion.

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

The MAX3362 has a 1/8-unit-load receiver input impedance, allowing up to 256 transceivers to be connected simultaneously on a single bus.

How is the low-power shutdown mode activated?

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