MAX1406EWE+T

__________Applications Information
Because the MAX1406 is not sensitive to power-supply
sequencing, no external protection diodes are required.
Any of the three supplies can power up first. However,
use proper layout techniques to ensure other devices
on your board are not damaged in case of an ESD
event.
Minimize the ground-lead return path to the power
supply, because currents as high as 60A can pass
into the ground.
Use a separate return path to the power supply.
Make trace widths greater than 40 mils.
• Bypass V
CC,
V
DD,
and V
SS
with 0.1µF capacitors as
close to the MAX1406 as possible to ensure maxi-
mum ESD protection.
• Tie any unused transmitter inputs to GND or V
CC
to
minimize power consumption.
