high as 60A can instantaneously pass into ground, so
be sure to minimize the ground-lead return path to the
power supply. A separate return path to the power sup-
ply is recommend. Trace widths should be greater than
40 mils. Bypass V

with 0.1μF capacitors
as close to the part as possible to ensure maximum
ESD protection.
The MAX3209E is not sensitive to power-supply
sequencing, and therefore requires no external protec-
tion diodes.
Interconnection with 3V and 5V Logic
The MAX3209E can directly interface with various 3V
and 5V logic families, including ACT and HCT CMOS.
See Table 1 for more information on possible combina-
tions of interconnections.
Mouse Driveability
The MAX3209E has been specifically designed to
power serial mice while operating from low-voltage
power supplies. It has been tested with leading mouse
brands from manufacturers such as Microsoft and
Logitech. The MAX3209E successfully drove all serial
mice tested and met their respective current and volt-
age requirements.
