Industry’s Smallest RS-485 Transceivers Save
Board Space and Reduce BOM Complexity
MAX13485E/MAX13486E, MAX13430E–MAX13433E
As industrial modules become smaller, pressure mounts for PLC designers
to shrink their PCBs and transition from the traditional industry-standard
packages like SO, SSOP, and PDIP. Maxim oers a full family of RS-485
transceivers available in tiny µDFN/TDFN packages with integrated
features that reduce BOM complexity, board space, and cost.
Benefits
MAX13485E/MAX13486E
• Smallest footprint enables compact
designs
◦ Space-saving, tiny 8-pin DFN
(2mm x 2mm) package
• High integration reduces BOM
complexity
◦ Hot-swap operation eliminates false
transitions during power-up/live
insertion
◦ Enhanced slew-rate limiting
facilitates error-free data
transmission
◦ Low-power shutdown modes
reduce power consumption during
idle operation
MAX13430E–MAX13433E
• Smallest footprint enables compact
designs
◦ Available in tiny 10-pin TDFN/µMAX
(3mm x 3mm) packages
• Flexible configurations for interfacing
to many applications, thus reducing
inventory
◦ 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
◦ High ±30kV (HBM) ESD protection
provides the industry’s most robust
protection
