transmitter is loaded with 3k
in parallel with 2500pF. Note
that the transmitters enable only when the magnitude of the
supplies exceed approximately 3V.
Mouse Driveability
The ICL3241E and ICL3243E have been specifically
designed to power a serial mouse while operating from low
voltage supplies. Figure 9 shows the transmitter output
voltages under increasing load current. The on-chip
switching regulator ensures the transmitters will supply at
least
±
5V during worst case conditions (15mA for paralleled
V+ transmitters, 7.3mA for single V- transmitter). The
Automatic Powerdown feature does not work with a mouse,
so FORCEOFF and FORCEON should be connected to V
CC
.
High Data Rates
The ICL32XXE maintain the RS-232
±
5V minimum
transmitter output voltages even at high data rates.
Figure 10 details a transmitter loopback test circuit, and
Figure 11 illustrates the loopback test result at 120kbps. For
this test, all transmitters were simultaneously driving RS-232
loads in parallel with 1000pF, at 120kbps. Figure 12 shows
the loopback results for a single transmitter driving 1000pF
and an RS-232 load at 250kbps. The static transmitters were
also loaded with an RS-232 receiver.
