High Data Rates
The ISL83385E maintains the RS-232
±
5V minimum
transmitter output voltages even at high data rates. Figure 4
details a transmitter loopback test circuit, and Figure 5
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 6 shows the
loopback results for a single transmitter driving 1000pF and
an RS-232 load at 250kbps. The static transmitter was also
loaded with an RS-232 receiver.
Interconnection with 3V and 5V Logic
The ISL83385E directly interfaces with most 5V logic
families, including ACT and HCT CMOS. See Table 4 for
more information on possible combinations of
interconnections.
±
15kV ESD Protection
All pins on the 3V interface devices include ESD protection
structures, but the ISL83385E incorporates advanced
structures which allow the RS-232 pins (transmitter outputs
and receiver inputs) to survive ESD events up to
±
15kV. The
RS-232 pins are particularly vulnerable to ESD damage
because they typically connect to an exposed port on the
exterior of the finished product. Simply touching the port
pins, or connecting a cable, can cause an ESD event that
might destroy unprotected ICs. These new ESD structures
protect the device whether or not it is powered up, protect
without allowing any latchup mechanism to activate, and
don’t interfere with RS-232 signals as large as
±
25V.
