meets Level 4 (the highest level) of IEC 1000-4-2, with-
out the need for additional ESD-protection compo-
nents.
The major difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2, because series resistance is
lower in the IEC 1000-4-2 model. Hence, the ESD with-
stand voltage measured to IEC 1000-4-2 is generally
lower than that measured using the Human Body
Model. Figure 7a shows the IEC 1000-4-2 model and
Figure 7b shows the current waveform for the 8kV,
IEC 1000-4-2, 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.

CMOS Switch Debouncers
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.
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.

the package code indicates RoHS status only. Package draw-
