GENERAL DESCRIPTION  
The ADM1491E is an RS-485 transceiver with 8 ꢀk ESD pro-  
tection and is suitable for high speed, full-duplex communication  
on multipoint transmission lines. In particular, the ADM1491E  
is designed for use in motor control applications requiring commu-  
nications at data rates up to 16 Mbps.  
Short-circuit protection circuits limit the maximum output  
current to 25ꢁ mA during fault conditions. A thermal shut-  
down circuit senses if the die temperature rises above 15ꢁ°C  
and forces the driver outputs into a high impedance state under  
this condition.  
The ADM1491E is designed for balanced transmission lines  
and complies with TIA/EIA-485-A-98. The device has a 12 ꢀΩ  
receiver input impedance for unit load RS-485 operation  
allowing up to 32 nodes on the bus.  
The receiver of the ADM1491E contains a fail-safe feature that  
results in a logic high output state if the inputs are unconnected  
(floating).  
The ADM1491E features extremely fast and closely matched  
switching times. Minimal driver propagation delays permit  
transmission at data rates up to 16 Mbps while low sꢀew  
minimizes EMI interference.  
The differential transmitter outputs and receiver inputs feature  
electrostatic discharge circuitry that provides protection to 8 ꢀk  
using the human body model (HBM).  
The ADM1491E operates from a single 5 k power supply. Exces-  
sive power dissipation caused by bus contention or output shorting  
is prevented by short-circuit protection and thermal circuitry.  
The ADM1491E is fully specified over the commercial and  
industrial temperature ranges and is available in two pacꢀages:  
a narrow-body 14-lead SOIC and a 1ꢁ-lead MSOP.
