Low-Voltage, Low-On-Resistance,
SPST, CMOS Analog Switches
_______________General Description
____________________________Features
ꢀ Available in SOT23-5 Package
The MAX4514/MAX4515 are single-pole/single-throw
(SPST), CMOS, low-voltage, single-supply analog
switches with very low switch on-resistance. The
MAX4514 is normally open (NO). The MAX4515 is nor-
mally closed (NC).
ꢀ +2V to +12V Single-Supply Operation
ꢀ Guaranteed On-Resistance:
20Ω with +5V Supply
10Ω with +12V Supply
These CMOS switches can operate continuously with a
single supply between +2V and +12V. Each switch can
handle rail-to-rail analog signals. The off-leakage cur-
rent maximum is only 1nA at +25°C or 20nA at +85°C.
ꢀ Guaranteed Low Off-Leakage Currents:
1nA at +25°C
20nA at +85°C
ꢀ Guaranteed Low On-Leakage Currents:
2nA at +25°C
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
+5V supply.
40nA at +85°C
ꢀ Low Charge Injection: 10pC
For pin-compatible parts for use with dual supplies, see
the MAX4516/MAX4517.

Note 1: Voltages exceeding V+ or GND 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.

Logic-Level Thresholds
__________Applications Information
The logic-level thresholds are CMOS/TTL compatible
when V+ is +5V. As V+ is raised, the level threshold
increases slightly. When V+ reaches +12V, the level
threshold is about 3.0V—above the TTL guaranteed
high-level minimum of 2.8V, but still compatible with
CMOS outputs.
Power-Supply Considerations
The MAX4514/MAX4515 construction is typical of most
CMOS analog switches, except that they have only two
supply pins: V+ and GND. V+ and GND drive the inter-
nal CMOS switches and set their analog voltage limits.
Reverse ESD-protection diodes are internally connect-
ed between each analog-signal pin and both V+ and
GND. One of these diodes conducts if any analog sig-
nal exceeds V+ or GND.
Do not connect the MAX4514/MAX4515’s V+ to +3V
and then connect the logic-level pins to logic-level
signals that operate from +5V supply. Output levels
can exceed +3V and violate the absolute maximum
ratings, damaging the part and/or external circuits.
Virtually all the analog leakage current comes from the
ESD diodes to V+ or GND. 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 V+ or GND and the analog signal. This
means their leakages will vary as the signal varies. The
difference in the two diode leakages to the V+ and GND
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 termi-
nal. This is why both sides of a given switch can show
leakage currents of the same or opposite polarity.
High-Frequency Performance
In 50Ω systems, signal response is reasonably flat up to
250MHz (see Typical Operating Characteristics). Above
20MHz, the on response has several minor peaks that
are highly layout dependent. The problem is not in turn-
ing the switch on; it’s in turning it off. The off-state switch
acts like a capacitor and passes higher frequencies with
less attenuation. At 10MHz, off isolation is about -45dB
in 50Ω systems, decreasing (approximately 20dB per
decade) as frequency increases. Higher circuit imped-
ances also make off isolation decrease. Off isolation is
about 3dB above that of a bare IC socket, and is due
entirely to capacitive coupling.
There is no connection between the analog-signal
paths and V+ or GND.
V+ and GND also power the internal logic and logic-
level translators. The logic-level translators convert the
logic levels to switched V+ and GND signals to drive
the analog signal gates.
