Quad, Rail-to-Rail, Fault-Protected,
SPST Analog Switches
General Description
The MAX312F/MAX313F/MAX314F are quad, single-
pole/single-throw (SPST), fault-protected analog switch-
es. They are pin compatible with the industry-standard
nonprotected MAX312/MAX313/MAX314. These switch-
es feature fault-protected inputs and Rail-to-Rail^ signal-
handling capability. All analog signal terminals are pro-
tected from overvoltage faults up to ±36V with power on
and up to ±40V with power off. During a fault condition,
the COM_, NO_, or NC_ terminal becomes an open cir-
cuit and only microamperes of leakage current flow from
the source. On-resistance is 10Ω (max) and is matched
between switches to 0.5Ω (max) at +25°C.
The MAX312F has four normally closed (NC) switches.
The MAX313F has four normally open (NO) switches.
The MAX314F has two NC and two NO switches. These
CMOS switches operate with dual power supplies rang-
ing from ±4.5V to ±20V or a single supply between +9V
and +36V. All digital inputs have +0.8V and +2.4V logic
thresholds, ensuring both TTL and CMOS logic com-
patibility when using ±15V or a single +12V supply.
For supply voltages of ±5V, +5V, and +3V, refer to the
MAX4711/MAX4712/MAX4713 data sheet.
