MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the AD8184
is limited by the associated rise in junction temperature. The maxi-
mum safe junction temperature for plastic encapsulated devices is
determined by the glass transition temperature of the plastic,
approximately +150 C. Exceeding this limit temporarily may
cause a shift in parametric performance due to a change in the
stresses exerted on the die by the package. Exceeding a junction
temperature of +175 C for an extended period can result in
device failure.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8184 feature proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
ENABLE pin is grounded. IN0 and IN2 = +1 V dc, IN1 and IN3 = –1 V dc. A0 is driven with a 0 V to +5 V pulse, A1 is grounded. Measure transition time from 50% of the A0
ENABLE pin is driven with 0 V to +5 V pulse (with 3 ns edges). The state of the A0 and A1 pins determines which input is activated (refer to Table I). Set IN0 and IN2 = +1 V dc,
All inputs are grounded. A0 input is driven with 0 V to +5 V pulse, A1 is grounded. The output is monitored. Speeding the edges of the A0 pulse increases the glitch magnitude

While the AD8184 is internally short circuit protected, this may
not be sufficient to guarantee that the maximum junction tempera-
ture (+150 C) is not exceeded under all conditions. To ensure
proper operation, it is necessary to observe the maximum power
derating curves shown in Figure 2.
