High-Speed, Low-Voltage, CMOS Analog
Multiplexers/Switches
________________General Description
____________________________Features
The MAX4617/MAX4618/MAX4619 are high-speed, low-
voltage, CMOS analog ICs configured as an 8-channel
multiplexer (MAX4617), two 4-channel multiplexers
(MAX4618), and three single-pole/double-throw (SPDT)
switches (MAX4619).
ꢀ Fast Switching Times

ꢀ Pin Compatible with Industry-Standard
74HC4051/74HC4052/74HC4053 and
MAX4581/MAX4582/MAX4583
These CMOS devices can operate continuously with a
+2V to +5.5V single supply. Each switch can handle
Rail-to-Rail® analog signals. The off-leakage current is
ꢀ Guaranteed On-Resistance
10Ω max (+5V Supply)
only 1nA at T = +25°C and 10nA at T = +85°C.

20Ω max (+3V Supply)
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V supply.
ꢀ Guaranteed 1Ω On-Resistance Match Between
Channels (single +5V supply)
ꢀ Guaranteed Low Off-Leakage Current:
1nA at +25°C
ꢀ Guaranteed Low On-Leakage Current:
1nA at +25°C
ꢀ +2V to +5.5V Single-Supply Operation
ꢀ TTL/CMOS-Logic Compatible
ꢀ Low Crosstalk: <-96dB
ꢀ High Off-Isolation: <-93dB
ꢀ Low Distortion: <0.017% (600Ω)

Note 1: Voltages exceeding V
or GND on any analog signal terminal are clamped by internal diodes. Limit forward-diode current
CC
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.

The MAX4617/MAX4618/MAX4619 are pin compatible

= +3V the guaranteed minimum logic-high
threshold decreases to 2.0V
Power Supply
These devices operate from a single supply between
+2.5V and +5.5V. All of the bipolar precautions must be
observed. At room temperature, they actually “work”
with a single supply near or below +2V, although as
supply voltage decreases, switch on-resistance
becomes very high.
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 found on 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 MAX4617/MAX4618/MAX4619.
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 V
on first, followed by the logic
CC
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).

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 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 50Ω 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.
