ESD Test Conditions
ESD performance depends on several conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
Human Body Model
Figure 6 shows the Human Body Model, and Figure 7
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
resistor.
Power-Supply Considerations
The MAX4558/MAX4559/MAX4560 are typical of most
CMOS analog switches. They have three supply pins:
VCC, VEE, and GND. VCC and VEE drive the internal
CMOS switches and set the limits of the analog voltage
on every switch. Internal reverse ESD-protection diodes
connect between each analog signal pin and both VCC
and VEE. If any analog signal exceeds VCC or VEE, one
of these diodes conducts. The only currents drawn
from VCC or VEE during normal operation are the leak-
age currents of these ESD diodes.
Although the ESD diodes on a given signal pin are
identical and therefore fairly well balanced, they are
reverse biased differently. Each is biased by either VCC
or VEE and the analog signal. Their leakage currents
vary as the signal varies. The difference in the two
diode leakages to the VCC and VEE pins constitutes the
analog signal-path leakage current. All analog leakage
current flows between each input and one of the supply
terminals, not to the other switch terminal. This is why
both sides of a given switch can show leakage currents
of either the same or opposite polarity.
VCC and GND power the internal logic and logic-level
translators, and set the input logic limits. The logic-level
translators convert the logic levels into switched VCC
and VEE signals to drive the gates of the analog switch.
This drive signal is the only connection between the
logic supplies and logic signals and the analog sup-
plies. VCC and VEE have ESD-protection diodes to
GND.
The logic-level thresholds are TTL/CMOS compatible
when VCC is +5V. As VCC rises, the threshold increases
slightly. When VCC reaches +12V, the threshold is
about 3.1V (above the TTL-guaranteed high-level mini-
mum of 2.4V, but still compatible with CMOS outputs).
High-Frequency Performance
In 50
systems, signal response is reasonably flat up
to 50MHz (see
Typical Operating Characteristics).
Above 20MHz, the on response has several minor
peaks that are highly layout dependent. The problem is
not turning the switch on, but turning it off. The off-state
switch acts like a capacitor and passes higher frequen-
cies with less attenuation. At 1MHz, off-isolation is
about -68dB in 50
systems, becoming worse (approx-
imately 20dB per decade) as the frequency increases.
Higher circuit impedance also degrades off-isolation.
Adjacent channel attenuation is about 3dB above that
of a bare IC socket and is entirely due to capacitive
coupling.
