Figure 6a shows the transmitter output voltages under
increasing load current at +3.0V. Figure 6b shows a
typical mouse connection using the MAX3241E.
High Data Rates
The MAX3222E/MAX3232E/MAX3237E/MAX3241E/
MAX3246E maintain the RS-232 ±5V minimum transmit-
ter output voltage even at high data rates. Figure 7
shows a transmitter loopback test circuit. Figure 8
shows a loopback test result at 120kbps, and Figure 9
shows the same test at 250kbps. For Figure 8, all trans-
mitters were driven simultaneously at 120kbps into RS-
232 loads in parallel with 1000pF. For Figure 9, a single
transmitter was driven at 250kbps, and all transmitters
were loaded with an RS-232 receiver in parallel with
1000pF.
The MAX3237E maintains the RS-232 ±5.0V minimum
transmitter output voltage at data rates up to 1Mbps.
Figure 10 shows a loopback test result at 1Mbps with
MBAUD = V
CC
. For Figure 10, all transmitters were
loaded with an RS-232 receiver in parallel with 250pF.
Interconnection with 3V and 5V Logic
The MAX3222E/MAX3232E/MAX3237E/MAX3241E/
MAX3246E can directly interface with various 5V logic
families, including ACT and HCT CMOS. See Table 3
for more information on possible combinations of inter-
connections.
UCSP Reliability
The UCSP represents a unique packaging form factor
that may not perform equally to a packaged product
through traditional mechanical reliability tests. UCSP
reliability is integrally linked to the user
’
s assembly
methods, circuit board material, and usage environ-
ment. The user should closely review these areas when
considering use of a UCSP package. Performance
through Operating Life Test and Moisture Resistance
remains uncompromised as the wafer-fabrication
process primarily determines it.
Mechanical stress performance is a greater considera-
tion for a UCSP package. UCSPs are attached through
direct solder contact to the user
’
s PC board, foregoing
the inherent stress relief of a packaged product lead
frame. Solder joint contact integrity must be consid-
ered. Table 4 shows the testing done to characterize
the UCSP reliability performance. In conclusion, the
UCSP is capable of performing reliably through envi-
ronmental stresses as indicated by the results in the
table. Additional usage data and recommendations are
detailed in the UCSP application note, which can be
found on Maxim

s website at www.maxim-ic.com.
