MAX4677/MAX4678/
MAX4679
2Ω, Quad, SPST, CMOS Analog Switches
General Description
Features
● On-Resistance 1.6Ω max
The MAX4677/MAX4678/MAX4679 quad analog switches
feature 1.6Ω max on-resistance (RON) when operating
from a dual ±5V supply. RON is matched between channels to 0.3Ω max and is flat (0.4Ω max) over the specified signal range. Each switch can handle Rail-to-Rail®
analog signals. Off-leakage current is 0.1nA at +25°C.
These switches are ideal in low-distortion applications
and are the preferred solution over mechanical relays in
automated test equipment. They have low power requirements, require less board space, and are more reliable
than mechanical relays.
● On-Resistance Flatness 0.4Ω max
● On-Resistance Matching 0.3Ω max
● Dual ±2.7V to ±5.5V or Single +2.7V to +11V
Supply Range
● TTL/CMOS-Logic Compatible
● Crosstalk -84dB at 1MHz
● Off-Isolation -65dB at 1MHz
● -3dB Bandwidth: 66MHz
The MAX4677 has four normally closed (NC) switches,
and the MAX4678 has four normally open (NO) switches.
The MAX4679 has two NC and two NO switches and features guaranteed break-before-make switching.
● Rail-to-Rail Signal Range
Ordering Information
The MAX4677/MAX4678/MAX4679 operate from either
a single +2.7V to +11V or dual ±2.7V to ±5.5V supplies,
making them ideal for use in digital card applications and
single-ended 75Ω systems.
These devices feature a separate logic supply input that
operates from +2.7V to V+, allowing independent logic and
analog supplies.

Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
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 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
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.
Note 5: Leakage parameters are 100% tested at maximum-rated hot operating temperature and the highest supply voltage, and
guaranteed by correlation at +25°C.

Applications Information
Power-supply bypassing improves noise margin and prevents switching noise from propagating from the V+ upply
to other components. A 0.1μF capacitor connected from
V+ to GND is adequate for most applications.
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 V+ on first, then V-, then VL followed by the
logic inputs, NO_, NC_, or COM. If proper power-supply
sequencing is not possible, add two small signal diodes
(D1, D2) in series with the supply pins, and a Schottky
diode between V+ and VL for overvoltage protection
(Figure 1). Adding diodes reduces the analog signal range
to one diode drop below V+ and one diode drop above
V-, but does not affect the devices’ low switch resistance
and low leakage characteristics. Device operation is
unchanged, and the difference between V+ and V- should
not exceed 11V.
