Analog Switches
General Description
The MAX4659/MAX4660 are medium voltage CMOS
analog switches with a low on-resistance of 25Ω max
specifically designed to handle large switch currents.
With a switch capability of up to 200mA peak current
and 150mA continuous current (MAX4660), and up to
150mA peak current and 75mA continuous current
(MAX4659), these parts can switch loads as low as
50Ω. They can replace reed relays with a million times
the speed and a virtually unlimited number of lifetime
cycles. Normal power consumption is only 3mW,
whether the switch is on or off. These parts are
TTL/CMOS compatible and will switch any voltage with-
in their power-supply range.
The devices are single-pole/double-throw (SPDT)
switches. The MAX4659/MAX4660 contain one normally
closed (NC) switch and one normally open (NO) switch.
The MAX4659/MAX4660s’ power-supply range is from
±4.5V to ±20V for dual-supply operation and +9V to
+40V for single-supply operation. These switches can
operate from any combination of supplies, within a 40V
V+ to V- range. They conduct equally well in either
direction and can handle rail-to-rail analog signals. The
off-leakage current is only 1nA max at T
A
= +25°C. The
MAX4659 is available in 8-pin µMAX® and SO pack-
ages. The MAX4660 is available in thermally enhanced
exposed paddle µMAX and SO packages.

Note 1:
Signals on NO, NC, COM, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maxi-
mum 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.

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
