their leakages will vary as the signal varies. The differ-
ence in the two-diode leakages to the V+ and GND
pins constitutes the analog-signal-path leakage current.
All analog leakage current flows between each pin and
one of the supply terminals, not to the other switch ter-
minal, which is why both sides of a given switch can
show leakage currents of either the same or opposite
polarity.
V+ and GND power the internal logic and set the input
logic limits. Logic inputs have ESD-protection diodes to
ground.
The logic-level thresholds are TTL/CMOS compatible
when V+ is +5V. As V+ rises, the threshold increases;
as V+ falls, the threshold decreases. For example,
when V+ = +3V, the guaranteed minimum logic-high
threshold decreases to 2.0V.
Low-Voltage Operation
The MAX4674 operates from a single supply between
+1.8V and +5.5V. At room temperature, it actually
“works” with a single supply near or below +1.7V; as
supply voltage decreases, however, switch on-resis-
tance becomes very high.
Overvoltage Protection
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings because stresses beyond the listed rat-
ings can cause permanent damage to the device.
Always sequence V+ on first, followed by the logic
inputs and analog signals. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with the supply pins for overvoltage protection
(Figure 1).
Adding diodes reduces the analog-signal range to one
diode drop below V+ and one diode drop above GND,
but does not affect the device’s low switch resistance
and low leakage characteristics. Device operation is
unchanged, and the difference between V+ and GND
should not exceed 6V. These protection diodes are not
recommended if signal levels must extend to ground.
High-Frequency Performance
In 50
systems, signal response is reasonably flat up
to 50MHz (see the 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 10MHz, off-isolation is
about -50dB in 50
systems, becoming worse (approx-
imately 20dB per decade) as frequency increases.
Higher circuit impedances also degrade off-isolation.
Adjacent channel attenuation is about 3dB above that
of a bare IC socket and is entirely due to capacitive
coupling.
