Low-Voltage, CMOS Analog
Multiplexers/Switches
General Description
The MAX4051/MAX4052/MAX4053 and MAX4051A/
MAX4052A/MAX4053A are low-voltage, CMOS analog
ICs configured as an 8-channel multiplexer (MAX4051/A),
two 4-channel multiplexers (MAX4052/A), and three sin-
gle-pole/double-throw (SPDT) switches (MAX4053/A).
The A-suffix parts are fully characterized for on-resistance
match, on-resistance flatness, and low leakage.
These CMOS devices can operate continuously with
dual power supplies ranging from ±2.7V to ±8V or a
single supply between +2.7V and +16V. Each switch
can handle rail-to-rail analog signals. The off-leakage
current is only 0.1nA at +25°C or 5nA at +85°C
(MAX4051A/MAX4052A/MAX4053A).
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using
±5V or a single +5V supply.

Note 1: Signals on any terminal exceeding V+ or V- 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 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
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., VNO = 3V to 0V and 0V 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.
