meets Level 4 (the highest level) of IEC1000-4-2, with-
out the need for additional ESD-protection compo-
nents.
The major difference between tests done using the
Human Body Model and IEC1000-4-2 is higher peak
current in IEC1000-4-2, because series resistance is
lower in the IEC1000-4-2 model. Hence, the ESD with-
stand voltage measured to IEC1000-4-2 is generally
lower than that measured using the Human Body
Model. Figure 7a shows the IEC1000-4-2 model and
Figure 7b shows the current waveform for the 8kV,
IEC1000-4-2, 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.
MAX 6818 μP Interfac ing
The MAX6818 has an output enable (
EN
) input that
allows switch outputs to be three-stated on the μP data
bus until polled by the μP. Also, state changes at the
switch inputs are detected, and an output (
CH)
goes low
after the debounce period to signal the μP. Figure 4
shows the timing diagram for enabling outputs and read-
ing data. If the output enable is not used, tie
EN
to GND
to “always enable’’ the switch outputs. If
EN
is low,
CH
is
always high. If a change of state is not required, leave
CH
unconnected.
