SP3223EB/3243EB +3.0V to +5.5V RS-232 Transceivers
Copyright 2004 Sipex Corporation
The SP3223EB and SP3243EB drivers can main-
tain high data rates up to 250kbps fully loaded.
Figure 17
.
shows a loopback test circuit used to
test the SP3243EB RS-232 Drivers.
Figure 18
shows the test results of the loopback circuit with
all three drivers active at 120kbps with typical
RS-232 loads in parallel with 1000pF capacitors.
Figure 19
shows the test results where one driver

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.
Figure 17. Loopback Test Circuit for RS-232 Driver
Data Transmission Rates
was active at 250kbps and all three drivers loaded
with an RS-232 receiver in parallel with a 1000pF
capacitor. A solid RS-232 data transmission
rate of 250kbps provides compatibility with many
designs in personal computer peripherals and
LAN applications.
Receivers
The receivers convert
±
5.0V EIA/TIA-232
levels to TTL or CMOS logic output levels. All
receivers have an inverting output that can be
disabled by using the EN pin.
