details a transmitter loopback test circuit, and Figure 6
illustrates the standard speed loopback test result for a
single transmitter driving 1000pF and an RS-232 load at
250kbps. Figure 7 shows the megabaud loopback results for
a single transmitter driving 250pF and an RS-232 load at
1Mbps. The static transmitters were also loaded with an
RS-232 receiver.
Interconnection with 3V and 5V Logic
The ICL3237 directly interfaces with most 5V logic families,
including ACT and HCT CMOS. See Table 4 for more
information on possible combinations of interconnections.
