Active quad RS422/RS485 driver in a 16-SOIC
The MAX3041ESE+ is an active-production quad RS422/RS485 line driver from Analog Devices, still in current manufacture. It packs four drivers into a single 16-SOIC package, making it a compact choice for differential bus interfaces where you need to drive multiple lines from one chip.
What the 2.5 Mbps data rate means for your bus
Rated at 2.5 Mbps, this driver comfortably handles RS422/RS485 links running at common industrial baud rates like 115.2 kbps, 921.6 kbps, or even 1 Mbps with margin. The 4/0 driver/receiver count means it is a pure driver — no onboard receivers — so you pair it with separate RS485 receivers on the bus.
Temperature range and field-fit check
No special handling beyond standard ESD precautions; the SOIC-16 package is a straightforward hand-solder or reflow job, no hot-air station needed.
