DG411F/DG412F/
DG413F
Quad, Rail-to-Rail, Fault-Protected,
SPST Analog Switches
General Description
Benefits and Features
● No Power-Supply Sequencing Required
The DG411F/DG412F/DG413F are quad, single-pole/sin-
gle-throw (SPST), fault-protected analog switches. They
are pin compatible with the industry-standard nonprotect-
ed DG411/DG412/DG413. These new switches feature
● Rail-to-Rail Signal Handling
● All Switches Off with Power Off
®
● All Switches Off when V+ is Off and V- is On
● ±40V Fault Protection with Power Off
● ±36V Fault Protection with ±15V Supplies
fault-protected inputs and Rail-to-Rail signal-handling
capability. All terminals are protected 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 circuit and only microamperes
of leakage current flow from the source. On-resistance
is 35Ω (max) and is matched between switches to 1.5Ω
(max) at +25°C.
● Control Line Fault Protection from
V- - 0.3V to V- + 40V
● Pin Compatible with Industry-Standard
DG411/DG412/DG413
The DG411F has four normally closed (NC) switches.
The DG412F has four normally open (NO) switches. The
DG413F has two NC and two NO switches. These CMOS
switches operate with dual power supplies ranging 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 compatibility when
using ±15V or a single +12V supply.
● 20ns (typ) Fault Response Time
● 35Ω (max) R
with ±15V Supplies
ON
● ±4.5V to ±20V Dual Supplies
● +9V to +36V Single Supply
● TTL- and CMOS-Compatible Logic Inputs with
±15V or Single +9V to +15V Supplies
For supply voltages of ±5V, +5V, and +3V, refer to the
MAX4711/MAX4712/MAX4713 data sheet.
