Benefits
MAX13485E/MAX13486E
• Smallest footprint enables compact
designs
– Space-saving, tiny 8-pin μDFN
(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)
field-programmable gate arrays (FPGAs)
and application-specific ICs (ASICs)
– Enhanced slew-rate limiting facilitates
error-free data transmission
– High ±30kV (HBM) ESD protection
provides the industry’s most robust
protection
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 offers
a full family of RS-485 transceivers available in tiny µDFN/TDFN
packages with integrated features that reduce BOM complexity,
board space, and cost.
Industry’s smallest RS-485 transceivers save board space and reduce BOM complexity
Packaged in a µDFN, the MAX13485E saves more than 50% board space compared to the competition.
