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 5V CMOS and TTL
logic families. Nevertheless, with the device at 3.3V, and the
logic supply at 5V, AC, HC, and CD4000 outputs can drive
ISL83385E inputs, but ISL83385E outputs do not reach the
minimum VIH for these logic families. See Table 4 for more
information.
