Part Description Features Benefits
Interface transceivers
MAX14770 PROFIBUS transceiver ±35kV (HBM) ESD tolerance; -40°C to +125°C
automotive temperature range; small (3mm x
3mm) TQFN package
Industry’s highest ESD protection makes
PLC more robust
MAX13450E/51E RS-485 transceivers with pin-selectable
termination resistors
Integrated 100Ω and 120Ω termination resistors;
FAULT indication; flexible logic interface
Allow remote configuration of the line
termination, which simplifies system
installation
MAX3535E Isolated RS-485 transceiver 3V to 5V operation; 2500V
RMS
isolated RS-485/
RS-422 transceivers; ±15kV ESD protection
Eliminates the need for external isolation
components
MAX13442E/43E/44E Fault-protected RS-485 transceivers ±80V fault protected half-duplex operation; 5V
transceivers (250kHz/10MHz)
Simplify design by eliminating external
components such as TVSs and PTCs
MAX13430E RS-485 transceiver with V
L
pin in tiny µDFN 3.3V to 5V operation; integrated V
L
pin (down to
1.6V); 10-pin µMAX/µDFN packages
Tiny packages with integrated V
L
pin save
board space; V
L
pin communicates with
low-voltage FPGAs and microcontrollers
MAX253 Transformer driver for isolated power with
RS-485/PROFIBUS interfaces
Single 5V or 3.3V supply; low-current shutdown
mode: 0.4µA; pin-selectable frequency of
350kHz or 200kHz; µMAX package
Simple open-loop circuit speeds power-
supply design and shortens time to market
MAX3107 SPI/I
2
C UART with integrated oscillators 24Mbps (max) data rate; 128B FIFOs; automatic
RS-485 transceiver control; 4 GPIOs; 24-pin
SSOP or small 3.5mm x 3.5mm TQFN packages
Serial interface and large FIFOs with
high integration reduce performance
requirements and cost of host controllers
