Maxim MAX4583ESE Low-voltage, cmos analog multiplexers/switch Datasheet

19-1328; Rev 1; 10/99
Low-Voltage, CMOS Analog
Multiplexers/Switches
____________________________Features
The MAX4581/MAX4582/MAX4583 are low-voltage,
CMOS analog ICs configured as an 8-channel multiplexer
(MAX4581), two 4-channel multiplexers (MAX4582), and
three single-pole/double-throw (SPDT) switches
(MAX4583).
These CMOS devices can operate continuously with
±2V to ±6V dual power supplies or a +2V to +12V single supply. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 1nA at
+25°C or 5nA at +85°C.
♦ Pin Compatible with Industry-Standard
74HC4051/74HC4052/74HC4053 and
MAX4051/MAX4052/MAX4053
♦ Offered in Automotive Temperature Range
(-40°C to +125°C)
♦ Guaranteed On-Resistance:
80Ω with ±5V Supplies
150Ω with Single +5V Supply
♦ Guaranteed On-Resistance Match Between
Channels
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V or dual ±5V supplies.
♦ Guaranteed Low Off-Leakage Current:
1nA at +25°C
♦ Guaranteed Low On-Leakage Current:
1nA at +25°C

Note 1: Voltages exceeding VCC or VEE on any signal terminal are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 3: ∆RON = RON(MAX) - RON(MIN).
Note 4: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified
analog signal ranges; i.e., VX_, VY_, VZ_ = 3V to 0 and 0 to -3V.
Note 5: Leakage parameters are 100% tested at maximum-rated hot operating temperature, and guaranteed by correlation at TA = +25°C.
Note 6: Guaranteed by design, not production tested.

__________Applications Information
Power-Supply Considerations
Overview
The MAX4581/MAX4582/MAX4583 construction is typical of most CMOS analog switches. They have three
supply pins: VCC, VEE, and GND. VCC and VEE are used
to drive the internal CMOS switches and set the limits of
the analog voltage on any switch. Reverse ESDprotection diodes are internally connected between
each analog-signal pin and both VCC and VEE. If any
analog signal exceeds VCC or VEE, one of these diodes
will conduct. During normal operation, these and other
reverse-biased ESD diodes leak, forming the only current drawn from VCC or VEE.
8
Virtually all the analog leakage current comes from the
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. This means their
leakages will 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 pin 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.
There is no connection between the analog-signal
paths and GND.

Note: Input and output pins are identical and interchangeable. Either may be considered an input or output; signals pass equally
well in either direction.
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 signals. This drive signal is the only connection between
the logic supplies and signals and the analog supplies.
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, so when VCC reaches +12V the threshold is
about 3.1V (above the TTL-guaranteed high-level minimum of 2.8V, but still compatible with CMOS outputs).
Bipolar Supplies
These devices operate with bipolar supplies between
±2V and ±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 “work” 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 maximum ratings because stresses beyond the listed ratings 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’ 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 50Ω 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 offstate switch acts like a capacitor and passes higher
frequencies with less attenuation. At 10MHz, off isolation is about -50dB in 50Ω systems, becoming worse
(approximately 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.
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 diagrams, although these parts differ electrically.

The pin designations and logic diagrams in this data
sheet conform to the original 1972 specifications published 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’s 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.
