Industry’s Smallest RS-485 Transceivers Save
Board Space and Reduce BOM Complexity
MAX13430E–MAX13433E
As industrial modules become smaller, pressure mounts for PLC designers to shrink
their designs and transition away from the traditional industry-standard packages like
SO, SSOP, and PDIP. Maxim oers a full family of RS-485 transceivers available in tiny
µMAX/TDFN packages with integrated features that reduce BOM complexity, board
space, and cost.
Benefits
• Smallest footprint enables compact
designs
◦ Available in tiny 10-pin TDFN/µMAX
(3mm x 3mm) packages
• Flexible configuration allows design
reuse
◦ Wide 3V to 5V supply reduces need
for 5V supply
◦ Integrated V
L
pin allows interface
with low-voltage logic (down to
1.62V logic) FPGAs and ASICs
◦ Enhanced slew-rate limiting
facilitates error-free data
transmission on improperly
terminated lines
• Robust in harsh environments
◦ High ±30kV (HBM) ESD provides
the industry’s most robust ESD
protection
◦ Hot-swap inputs
◦ -40°C to +85°C operation with
thermal shutdown protection
