FailꢁSafe RSꢁ4±ꢀ/J178± Transceivers  
General Description  
Features  
The MAX13442E/MAX13444E are fault-protected RS-485  
and J1708 transceivers that feature 80V protection from  
signal faults on communication bus lines. The  
MAX13442E/MAX13444E feature a reduced slew-rate dri-  
ver that minimizes EMI and reflections, allowing error-free  
transmission up to 250kbps. The MAX13443E driver can  
transmit up to 10Mbps. The high-speed MAX13443E  
RS-485 tranceiver features ±±0V protection from signal  
faults on communication bus lines. These transceivers fea-  
ture foldback current limit. Each device contains one dif-  
ferential line driver with three-state output and one  
differential line receiver with three-state input. The 1/4-unit-  
load receiver input impedance allows up to 128 trans-  
ceivers on a single bus. The devices operate from a 5V  
supply. True fail-safe inputs guarantee a logic-high receiv-  
er output when the receiver inputs are open, shorted, or  
connected to an idle data line.

Hot-swap circuitry eliminates false transitions on the  
data bus during circuit initialization or connection to a  
live backplane. Short-circuit current-limiting and ther-  
mal-shutdown circuitry protect the driver against exces-  
sive power dissipation, and on-chip 15kV ESD  
protection eliminates costly external protection devices.  
The MAX13442E/MAX13443E/MAX13444E are avail-  
able in an 8-pin SO package and are specified over the  
automotive temperature range.
