What is MAX14891EATP+ used for?
The MAX14891EATP+ is designed for industrial automation and process control systems where multiple RS-485 or RS-422 differential data lines must be received simultaneously on a single IC. It fits naturally into PLCs, motor drives, and sensor networks that aggregate data from several remote nodes over long cable runs in noisy environments. The compact 20-TQFN package and quad-channel integration reduce board area and BOM cost in multi-node field-bus interface cards.

Frequently Asked Questions
How many RS-485 receiver channels does the MAX14891EATP+ integrate and what is its package size?
The MAX14891EATP+ integrates 4 independent RS-485/RS-422 line receiver channels in a single 20-pin TQFN package measuring 4 mm × 4 mm × 0.75 mm. This quad integration reduces board footprint compared to using four individual single-channel receiver ICs, which is particularly valuable in space-constrained industrial I/O modules and fieldbus interface cards.
What output drive capability does MAX14891EATP+ provide and how does it interface with 3.3 V logic?
The MAX14891EATP+ delivers up to 3 mA output low current per channel with true output polarity, making it directly compatible with 3.3 V CMOS logic inputs on microcontrollers and FPGAs. No additional level-shift circuitry is needed when interfacing received RS-485 differential signals to a standard 3.3 V digital system, simplifying the overall design and reducing external component count.
When would an engineer choose MAX14891EATP+ over a dual-channel RS-485 receiver for a PLC input card?
An engineer would select the MAX14891EATP+ when 4 or more RS-485 channels are needed on a single PCB because integrating all 4 receivers in one 20-TQFN footprint cuts board area by roughly 50% and reduces solder joints compared to two dual-channel devices. For PLC analog or digital input modules handling 4 sensor nodes at data rates common in industrial fieldbus applications, the MAX14891EATP+ simplifies layout and lowers assembly cost.
