Product details

What this RS422/RS485 driver actually does

The MAX3030EESE+T from Analog Devices (formerly Maxim Integrated) is a quad RS422/RS485 line driver — four drivers on one die, zero receivers. It is a pure transmit-side device, not a transceiver, so you pair it with a separate RS485 receiver or a transceiver that handles the receive half. The 20Mbps data rate puts it in the high-speed tier for RS485, suitable for Profibus or backplane serial links where you need to push data fast over a differential pair. Supply range is 3V to 3.6V, which means it runs cleanly on a 3.3V rail. The 3.0V floor is worth noting — if your system has a 3.0V rail that droops under load, this driver still operates within spec down to that edge. Operating temperature covers -40°C to 85°C, the industrial grade, so it fits factory-floor PLCs, outdoor telecom gear, and HVAC controllers that see temperature swings.

Lifecycle and sourcing posture

That means no last-time-buy scramble, no forced redesign for a replacement. ROHS3 compliant, so it passes the usual environmental compliance gates for EU and global markets.

Frequently asked questions

Can MAX3030EESE+T be used with a 3.0V supply for RS485 communication?

Yes. The supply voltage range is 3V to 3.6V, so a 3.0V rail is within the operating window. At 3.0V the driver output swing will be lower than at 3.3V, but it still meets the RS485 differential output spec as long as the supply stays above the minimum.

Can MAX3030EESE+T be used for RS422 at 20Mbps?

Yes. The device supports both RS422 and RS485 protocols, and the 20Mbps data rate is well within RS422's capability. RS422 is a point-to-point or multidrop topology with a single driver and multiple receivers, which matches this part's 4-driver configuration.

Is there a direct replacement or equivalent for MAX3030EESE+T from another brand?

No direct pin-compatible equivalent from another brand is listed in the available records. The MAX3030EESE+T is a Maxim (now Analog Devices) proprietary part. For a second source, look at the MAX3030 family from the same manufacturer — the base MAX3030EESE (without the T suffix) is the same die in a tube/tray package, functionally identical.
