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

Ω 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-

capacitor. To ensure full ±15kV ESD protection, bypass

tors as close to the power-supply inputs as possible.

datasheet.

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.
