IEC 61000-4-2
The IEC 61000-4-2 standard covers ESD testing and per-
formance of finished equipment; it does not specifically
refer to integrated circuits. The MAX13046E/MAX13047E
help to design equipment that meets Level 4 of IEC
61000-4-2 without the need for additional ESD-protection
components. The major difference between tests done
using the Human Body Model and IEC 61000-4-2 is high-
er peak current in IEC 61000-4-2 because series resis-
tance is lower in the IEC 61000-4-2 model. Hence, the
ESD withstand voltage measured to IEC 61000-4-2 can
be lower than that measured using the Human Body
Model. Figure 3a shows the IEC 61000-4-2 model, and
Figure 3b shows the current waveform for the ±8kV, IEC
61000-4-2, Level 4, ESD contact-discharge test. The Air-
Gap test involves approaching the device with a charged
probe. The contact-discharge method connects the
probe to the device before the probe is energized.
Applications Information
Power-Supply Decoupling
To reduce ripple and the chance of transmitting incor-
rect data, bypass V_L and V_CC to ground with a 0.1µF
ceramic capacitor. To ensure full ±15kV ESD protec-
tion, bypass V_CC to ground with a 1µF ceramic capaci-
tor. Place all capacitors as close as possible to the
power-supply inputs.
I²C Level Translation
The MAX13046E/MAX13047E level shifts the data pre-
sent on the I/O lines between +1.1V and +5.5V, making
them ideal for level translation between a low-voltage
ASIC and an I²C device. A typical application involves
interfacing a low-voltage microprocessor to a +3V or
+5V D/A converter, such as the MAX517.
1-Wire Interface Translation
The MAX13046E/MAX13047E are ideal for level transla-
tion between a low-voltage ASIC and 1-Wire device. A
