MAX3322E/MAX3323E
Power-Supply Decoupling
In most circumstances, a 0.1F bypass capacitor is ade-
quate. In applications sensitive to power-supply noise,
decouple VCC to ground with a capacitor of the same
value as charge-pump capacitor C1. Connect bypass
capacitors as close to the IC as possible.
High Data Rates
The MAX3322E/MAX3323E maintain the RS-232 ±5.0V
minimum transmitter output voltage even at high data
rates. Figure 10 shows a transmitter loopback test cir-
cuit. Figure 11 shows a loopback test result at
125kbps, and Figure 12 shows the same test at
250kbps. For Figure 11, all transmitters were driven
simultaneously at 125kbps into RS-232 loads in parallel
with 1000pF. For Figure 12, a single transmitter was dri-
ven at 250kbps, and all transmitters were loaded with
an RS-232 receiver in parallel with 1000pF.
Interconnection with 3V and 5V Logic
The MAX3322E/MAX3323E can directly interface with
various 5V logic families, including ACT and HCT
CMOS. The logic voltage power-supply pin VL sets the
output voltage level of the receivers and the input
thresholds of the transmitters.
