RS-232 Transceivers with Internal Capacitors

Each transmitter is loaded with 3k
in parallel with
1000pF. The transmitter outputs display no ringing or
undesirable transients as they come out of shutdown.
Note that the transmitters are enabled only when the
magnitude of V- exceeds approximately -3V.
High Data Rates
The MAX3233E/MAX3235E maintain the RS-232 ±5.0V
minimum transmitter output voltage even at high data
rates. Figure 8 shows a transmitter loopback test cir-
cuit. Figure 9 shows a loopback test result at 120kbps,
and Figure 10 shows the same test at 250kbps. For
Figure 9, all transmitters were driven simultaneously at
120kbps into RS-232 loads in parallel with 1000pF. For
Figure 10, a single transmitter was driven at 250kbps,
and all transmitters were loaded with an RS-232 receiv-
er in parallel with 250pF.
Interconnection with 3V and 5V Logic
The MAX3233E/MAX3235E can directly interface with
various 5V logic families, including ACT and HCT
CMOS. See Table 3 for more information on possible
combinations of interconnections.
