MAX4581/MAX4582/MAX4583
slightly, so when VCC reaches +12V the threshold is
about 3.1V (above the TTL-guaranteed high-level mini-
mum of 2.8V, but still compatible with CMOS outputs).
Bipolar Supplies
These devices operate with bipolar supplies between
卤2V and 卤5V. The VCC and VEE supplies need not be
symmetrical, but their sum cannot exceed the +13V
absolute maximum rating
Single Supply
These devices operate from a single supply between
+2V and +12V when VEE is connected to GND. All of
the bipolar precautions must be observed. At room
temperature, they actually 鈥渨ork鈥� with a single supply
near or below +1.7V, although as supply voltage
decreases, switch on-resistance and switching times
become 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 devices.
Always sequence VCC on first, then VEE, 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 VCC and one diode drop above VEE,
but does not affect the devices鈥� low switch resistance
and low leakage characteristics. Device operation is
unchanged, and the difference between VCC and VEE
should not exceed 13V. These protection diodes are
not recommended when using a single supply if signal
levels must extend to ground.
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 which 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
frequencies with less attenuation. At 10MHz, off isola-
tion is about -50dB in 50
systems, becoming worse
(approximately 20dB per decade) as frequency in-
creases. 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.
Pin Nomenclature
The MAX4581/MAX4582/MAX4583 are pin-compatible
with the industry-standard 74HC4051/74HC4052/
74HC4053 and the MAX4051/MAX4052/MAX4053.
They function identically and have identical logic dia-
grams, although these parts differ electrically.
The pin designations and logic diagrams in this data
sheet conform to the original 1972 specifications pub-
lished by RCA for the CD4051/CD4052/CD4053. These
designations differ from the standard Maxim switch and
mux designations as found all other Maxim data sheets
(including the MAX4051/MAX4052/MAX4053) and may
cause confusion. Designers who feel more comfortable
with Maxim鈥檚 standard designations are advised that
the pin designations and logic diagrams on the
MAX4051/MAX4052/MAX4053 data sheet may be freely
applied to the MAX4581/MAX4582/MAX4583.
