MAX14840E/MAX14841E 40Mbps, +3.3V, RS-485 Half-Duplex Transceivers  
General Description  
Benefits and Features  
High ESD Protection Provides Increases Equipment  
The MAX14840E/MAX14841E are +3.3V ESD-protected  
transceivers intended for half-duplex RS-485 communica-  
tion up to 40Mbps. These transceivers are optimized for  
high speeds over extended cable runs while maximizing  
tolerance to noise.  
Uptime  
• ±35kV Human Body Model (HBM) per JEDEC  
JS-001-2012  
• ±20kV Air Gap Discharge per IEC 61000-4-2  
• ±12kV Contact Discharge per IEC 61000-4-2  
The MAX14840E features symmetrical fail-safe and larg-  
er receiver hysteresis, providing improved noise rejection  
and improved recovered signals in high-speed and long  
cable applications. The MAX14841E has true fail-safe  
receiver inputs guaranteeing a logic-high receiver output  
when inputs are shorted or open.  
Integrated Features Increases Robustness  
• Large 170mV Receiver Hysteresis (MAX14840) for  
High Receiver Noise Tolerance  
• True Fail Safe Receiver Input (MAX14841E) Keeps  
Receiver Output Logic-High Upon Shorts and  
Open On Receiver Input  
• Thermal Self-Protection Shutdown at 160°C  
Junction Temperature  
• High Industrial -40°C to +125°C Ambient Operating  
Temperature Range/-40°C to +150°C Junction  
Temperature Range  
• Hot Swap Capability Eliminates False Transition  
During Power-Up or Hot Insertion  
The MAX14840E/MAX14841E are available in 8-pin SO  
and small, 8-pin (3mm x 3mm) TDFN-EP packages. Both  
devices operate over the -40NC to +125NC temperature  
range.  
Applications  
Motion Controllers  
Fieldbus Networks  
Industrial Control Systems  
Backplane Buses  
HVAC Networks  
Low Current Reduces Power Requirements  
• 10µA (max) Shutdown Current  
• 1.5mA (typ) Supply Current  
• 3.3V Supply Voltage  
Ordering Information/Selector Guide appears at end of data  
sheet.  
Available in Industry Standard 8-Pin SO or  
Space-Saving 8-Pin TDFN-EP (3mm x 3mm) Packages
