High Data Rates
The ISL83387E maintains the RS-232
±
5V minimum
transmitter output voltages even at high data rates. Figure 9
details a transmitter loopback test circuit, and Figure 10
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 11 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
Standard 3.3V powered RS-232 devices interface well with
3V and 5V powered TTL compatible logic families (e.g., ACT
and HCT), but the logic outputs (e.g., R
OUTS
) fail to reach
the V
IH
level of 5V powered CMOS families like HC, AC, and
CD4000. The ISL83387E V
L
supply pin solves this problem.
By connecting V
L
to the same supply (1.8V to 5V) powering
the logic device, the ISL83387E logic outputs will swing from
GND to the logic V
CC
.
±
15kV ESD Protection
All pins on the 3V interface devices include ESD protection
structures, but the ISL83387E
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
