Driving the MAX3212 from 5V Logic
The MAX3212 can directly interface with various 5V
logic families, including ACT and HCT CMOS.
Mouse Driveability
The MAX3212 has been specifically designed to power
serial mice while operating from low-voltage power sup-
plies. It has been tested with samples of ten major
mouse models from six manufacturers, including the
leading three, Logitech (5 models), Mouse Systems,
and Microsoft. The MAX3212 successfully drove all ser-
ial mice and met their respective current and voltage
requirements.
Figure 6 shows the transmitter output voltages under
increasing load current. The MAX3212’s switching reg-
ulator ensures the transmitters will supply at least ±5V
during worst-case load conditions.
