MAX3042BCWE+T

Overview

The MAX3042BCWE+T is a quad transmitter integrated circuit designed for RS-485 and RS-422 communication interfaces. It operates at a fixed supply voltage of 5 V with a maximum data rate of 20 Mb/s. The device features ±10 kV human-body model ESD protection on the bus pins, ensuring robustness in electrically noisy environments. It utilizes an SO-Wide-16 package and supports an operating temperature range from -40°C to +85°C. Key electrical parameters include a propagation delay of 23 ns, a power dissipation of 762 mW, and a quiescent current of 1 mA.

Feature Summary

• Provides four differential drivers compatible with RS-485 and RS-422 standards.
• Integrates high-level electrostatic discharge protection directly on the bus lines.
• Supports high-speed data transmission up to 20 megabits per second.
• Operates reliably across extended industrial temperature ranges.

Applications

• Industrial automation control networks
• Building automation systems
• Process control instrumentation

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact thermal grade and packaging specifications. Ensure compatibility with existing board layouts regarding the SO-Wide-16 footprint dimensions. Confirm RoHS compliance status through the manufacturer's current product change notices before finalizing procurement orders.

Selection Notes

Select this component when designing multi-drop serial communication links requiring high noise immunity. The integrated ESD protection reduces the need for external transient suppression components. Verify that the system logic levels are compatible with the 5 V operation requirement. Consider the thermal characteristics if multiple units are placed in close proximity within the enclosure.
