0.4Ω, Low-Voltage, Single-Supply
SPST Analog Switches in SC70
General Description
The MAX4715/MAX4716 are low on-resistance, low-
voltage, single-pole/single-throw (SPST) analog switch-
es that operate from a +1.6V to +3.6V single supply.
The MAX4715 is normally open (NO), and the MAX4716
is normally closed (NC). These devices also have fast
switching speeds (t
ON
= 18ns max, t
OFF
= 12ns max).
When powered from a +3V supply, the MAX4715/
MAX4716 offer 0.4Ω max on-resistance (R
ON
) with 0.1Ω
max R
ON
flatness. Their digital logic inputs are +1.8V
CMOS compatible when using a single +3V supply.
The MAX4715 is pin compatible with the MAX4594, and
the MAX4716 is pin compatible with the MAX4595. The
MAX4715/MAX4716 are available in SC70-5 packages.

Note 1:
Signals on NO, NC, or COM exceeding V+ or GND are clamped by internal diodes.
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:
SC70-packaged parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and
correlation.
Note 4:
Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the
specified analog signal range.
