±15kV ESD-Protected, Single/Dual/Octal,

CMOS Switch Debouncers

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 withstand volt-

age 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 ener-

gized.

Machine Model

The Machine Model for ESD tests all pins using a 200pF

storage capacitor and zero discharge resistance. Its

objective is to emulate the stress caused by contact that

occurs with handling and assembly during manufacturing.

MAX6818 µP Interfacing

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

reading 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.
