Product details

Quad RS-422/RS-485 line driver — 20 Mbps, industrial temp, active production

The Maxim MAX3042BEUE+ is a quad-channel RS-422/RS-485 line driver in a compact 16-TSSOP package. It delivers four independent driver outputs with a differential data rate of 20 Mbps, making it suitable for high-speed point-to-point or multi-drop serial links in factory automation, building control, and telecom infrastructure. The device operates from a single 4.75 V to 5.25 V supply and is rated over the industrial temperature range of -40°C to 85°C, covering outdoor and unconditioned indoor environments.

20 Mbps signaling — cable-length trade-off

At 20 Mbps, the MAX3042BEUE+ supports short-haul RS-485 links. The driver outputs are differential, providing common-mode noise rejection critical in industrial environments with motor drives and inverters.

Lifecycle: active, no EOL concern

For BOM planning, there is no last-time-buy risk or forced redesign horizon.

Sourcing posture — quoted to order

Pricing and availability are confirmed at quote time through independent distribution. We source this part against an RFQ — no stock figures are published here because the channel position changes daily. Submit an RFQ for current price, lead time, and date-code options.

Frequently asked questions

What is the difference between MAX3042BEUE+ and MAX3042EUE+?

The difference is in the temperature grade. The MAX3042BEUE+ is rated for the industrial temperature range of -40°C to 85°C, while the MAX3042EUE+ is typically the extended-industrial version. Pin-compatible, same 20 Mbps data rate and 4/0 driver count. For designs requiring the wider temperature range, the 'B' variant is the correct choice.

What is the equivalent of MAX3042BEUE+?

Within the Maxim family, the MAX3042BEUE+ is the industrial-temperature version. The MAX3042EUE+ is the standard-temperature sibling. Both are pin-compatible and functionally identical. For a second-source, look at TI's SN65HVD3082E series or Analog Devices' ADM3485E — but verify pinout and supply range against your layout.
