Operation down to 2.7V
ICL32X7E transmitter outputs meet RS-562 levels (±3.7V)
with VCC as low as 2.7V. RS-562 levels typically ensure inter
operability with RS-232 devices.
High Data Rates
The ICL32XX maintain the RS-232 ±5V minimum transmitter
output voltages even at high data rates. Figure 7 details a
transmitter loopback test circuit, and Figure 8 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 9 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 ICL32X7E directly interface with 5V CMOS and TTL
logic families. Nevertheless, with the ICL32X7E at 3.3V, and
the logic supply at 5V, AC, HC, and CD4000 outputs can
drive ICL32X7E inputs, but ICL32X7E outputs do not reach
more information.
±15kV ESD Protection
All pins on ICL32XX devices include ESD protection
structures, but the ICL32X7E incorporate 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.
