to design equipment that meets Level 4 of IEC 61000-
4-2 without the need for additional ESD-protection com-
ponents.
The major difference between tests done using the
Human Body Model and IEC 61000-4-2 is higher peak
current in IEC 61000-4-2 because series resistance is
lower in the IEC 61000-4-2 model. Hence, the ESD
withstand voltage measured to IEC 61000-4-2 is gener-
ally 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.
Machine Model
The Machine Model for ESD tests all pins using a
200pF storage capacitor and zero discharge resis-
tance. Its objective is to emulate the stress caused by
contact that occurs with handling and assembly during
manufacturing. Of course, all pins require this protec-
tion during manufacturing, not just inputs and outputs.
Therefore, after PCB assembly, the Machine Model is
less relevant to I/O ports.
Applications Information
Power-Supply Decoupling
To reduce ripple and the chance of transmitting incorrect
data, bypass VL and VCC to ground with a 0.1F capaci-
tor (see the Typical Application Circuit). To ensure full
±15kV ESD protection, bypass VCC to ground with a 1F
capacitor. Place all capacitors as close as possible to
the power-supply inputs.
I2C Level Translation
The MAX3397E level-shifts the data present on the I/O
lines between +1.2V 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 convert-
er, such as the MAX517.
Push-Pull vs. Open-Drain Driving
The MAX3397E can be driven in a push-pull configura-
tion and include internal 10k
Ω resistors that pull up I/O
VL_ and I/O VCC_ to their respective power supplies,
allowing operation of the I/O lines with open-drain
devices. See the Timing Characteristics table for maxi-
mum data rates when using open-drain drivers.
