Chip Information
PROCESS: BiCMOS
High Data Rates
The MAX13234E–MAX13237E maintain the RS-232 ±5V
minimum transmitter output voltage even at high data
rates. Figure 11 shows a transmitter loopback test cir-
cuit. Figure 12 shows a loopback test result at
120kbps, and Figure 13 shows the same test at 3Mbps.
In Figure 12, all transmitters were driven simultaneously
at 120kbps into RS-232 loads in parallel with 1000pF.
In Figure 13, a single transmitter was driven at 3Mbps,
and all transmitters were loaded with an RS-232 receiv-
er in parallel with 150pF.
