DG411F - SPST Analog Switches

Description

The DG411F/DG412F/DG413F are quad, single-pole/single-throw (SPST), fault-protected analog switches.

They are pin compatible with the industry-standard nonprotected DG411/DG412/DG413.

These new switches feature fault-protected inputs and Rail-to-Rail signalhandling capability.

Features

  • o No Power-Supply Sequencing Required o Rail-to-Rail Signal Handling o All Switches Off with Power Off o All Switches Off when V+ is Off and V- is On o ±40V Fault Protection with Power Off o ±36V Fault Protection with ±15V Supplies o Control Line Fault Protection from V- - 0.3V to V- + 40V o Pin Compatible with Industry-Standard DG411/DG412/DG413 o 20ns (typ) Fault Response Time o 35Ω (max) RON with ±15V Supplies o ±4.5V to ±20V Dual Supplies o +9V to +36V Single Supply o TTL- and CMOS-Compatibl.

19-2418; Rev 0; 4/02 DG411F/DG412F/DG413F Quad, Rail-to-Rail, Fault-Protected, SPST Analog Switches General Description The DG411F/DG412F/DG413F are quad, single-pole/single-throw (SPST), fault-protected analog switches. They are pin compatible with the industry-standard nonprotected DG411/DG412/DG413. These new switches feature fault-protected inputs and Rail-to-Rail signalhandling 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.
