Transmitter Outputs Recovering
from Shutdown
Figure 3 shows two transmitter outputs recovering from
shutdown mode. As they become active, the two trans-
mitter outputs are shown going to opposite RS-232 levels
(one transmitter input is high; the other is low). Each
transmitter is loaded with 3k
in parallel with 2500pF.
The transmitter outputs display no ringing or undesir-
able transients as they come out of shutdown. Note that
the transmitters are enabled only when the magnitude
of V- exceeds approximately -3.0V.
Mouse Drivability
The MAX3241E is designed to power serial mice while
operating from low-voltage power supplies. It has
been tested with leading mouse brands from manu-
facturers such as Microsoft and Logitech. The
MAX3241E successfully drove all serial mice tested
and met their current and voltage requirements.
