Figure 12
shows a loopback test circuit used to
test the RS-232 Drivers.
Figure 13
shows the test
results of the loopback circuit with all three
drivers active (SP3243) at 120Kbps with typical
RS-232 loads in parallel with 1000pF capacitors.
Figure 14
shows the test results where one driver
was active at 235Kbps and all three drivers
loaded with an RS-232 receiver in parallel with
a 1000pF capacitor. A solid RS-232 data trans-

Note: In AUTO ON-LINE
Mode where ONLINE =
GND and SHUTDOWN = V
, the device will shut down
if there is no activity present at the Receiver inputs.

Data Transmission Rates
mission rate of 120Kbps provides compatibility
with many designs in personal computer periph-
erals and LAN applications.
Receivers
The receivers convert
±
5.0V EIA/TIA-232
levels to TTL or CMOS logic output levels.
Receivers have an inverting output that can be
disabled by using the EN pin.
