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 Power-Down feature does
not work with a mouse, so FORCEOFF and FORCEON
should be connected to VCC.
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.
Interconnection with 3V and 5V
Logic
The ICL32XX directly interface with 5V CMOS and TTL
logic families. Nevertheless, with the ICL32XX at 3.3V,
and the logic supply at 5V, AC, HC, and CD4000 outputs
can drive ICL32XX inputs, but ICL32XX outputs do not
reach the minimum VIH for these logic families. See
Table 4 for more information.
