MAX3245E dual charge pump ensures the transmitters
will supply at least ±5V during worst-case conditions.
Figure 13b shows the transmitter output voltages under
increasing load current. Figure 13a shows a typical
mouse connection.
The MAX3224E–MAX3227E/MAX3244E/MAX3245E can
directly interface with various 5V logic families, includ-
ing ACT and HCT CMOS. See Table 4 for more infor-
mation on possible combinations of interconnections.
Table 5 lists other Maxim ESD-powered transceivers.
