ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
Figure 7a shows the Human Body Model and Figure 7b
shows the current waveform it generates when dis-
charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of inter-
est, which is then discharged into the test device
through a 1.5k
resistor.
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 PC board assembly, the Machine
Model is less relevant to I/O ports.
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
capacitor. To ensure full ±15kV ESD protection, bypass
V
CC
to ground with a 1μF capacitor. Place all capaci-
tors as close to the power-supply inputs as possible.

Unidirectional vs. Bidirectional Level
Translator
The MAX3000E/MAX3001E/MAX3002/MAX3003 can
also be used to translate signals without inversion.
These devices provide the smallest solution (UCSP
package) for unidirectional level translation without
inversion.
