General Description

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

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.

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.

For supply voltages of ±5V, +5V, and +3V, refer to the

MAX4711/MAX4712/MAX4713 data sheet.
