High-Speed, Single-Supply,
Quad, SPST Analog Switches
General Description
The MAX4591/MAX4592/MAX4593 are high-speed,
precision, quad, single-pole/single-throw (SPST) analog
switches designed to operate at +12V or +15V. The
MAX4591 has four normally closed (NC) switches, and
the MAX4592 has four normally open (NO) switches.
The MAX4593 has two NO and two NC switches. All
three devices offer low leakage (100pA max) and fast
switching speeds (t
ON
≤
80ns, t
OFF
≤
45ns).
With a +12V supply, the MAX4591/MAX4592/MAX4593
offer guaranteed 1Ω max channel-to-channel matching,
20Ω max on-resistance (R
ON
), and 1.75Ω max R
ON
flat-
ness over the specified range.
These switches are also fully specified for single +15V
operation, with 16Ω max R
ON,
1.5Ω max R
ON
match,
and 1.5Ω max flatness. For low-voltage or dual-supply
operation, refer to the MAX391 data sheet.
These low-voltage switches also offer 5pC max charge
injection, and electrostatic discharge (ESD) protection
is greater than 2000V, per Method 3015.7.

Note 1:
Signals on NC_, NO_, COM_, or IN_ 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.
