Datasheet

allel with 2500pF. 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 MAX3316–MAX3319 maintain RS-232-compatible
±3.7V minimum transmitter output voltage even at high
data rates. Figure 6 shows a transmitter loopback test
circuit. Figure 7 shows a loopback test result at
230kbps. For Figure 7, all transmitters were driven
simultaneously at 230kbps into EIA/TIA-562 loads in
parallel with 1000pF.
