High Data Rates
The ICL32XX maintain the RS-232
±
5V minimum transmitter
output voltages even at high data rates. Figure 10 details a
transmitter loopback test circuit, and Figure 11 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 12 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 ICL32XX directly interface with most 5V logic families,
including ACT and HCT CMOS. See Table 4 for more
information on possible combinations of interconnections.
