ADG5243F

Data Sheet User Defined Fault Protection and Detection, 0.8 pC QINJ, Triple SPDT ADG5243F FEATURES User defined supplies set overvoltage level Overvoltage protection up to −55 V and +55 V Power-off protection up to −55 V and +55 V Overvoltage detection on source pins Minimum secondary supply level: 4.5 V single-supply Interrupt flags indicate fault status Low charge injection (QINJ): 0.8 pC Low drain/source on capacitance: 10 pF Latch-up immune under any circumstance Known state without digital inputs present VSS to VDD analog signal range ±5 V to ±22 V dual supply operation 8 V to 44 V single-supply operation Fully specified at ±15 V, ±20 V, +12 V, and +36 V APPLICATIONS Analog input/output modules Process control/distributed control systems Data acquisition Instrumentation Avionics Automatic test equipment Communication systems Relay replacement GENERAL DESCRIPTION The ADG5243F comprises three independently selectable, singlepole/double-throw (SPDT) switches. All channels exhibit breakbefore-make switching action that prevents momentary shorting when switching channels. An EN input enables or disables the device. When disabled, all channels are switched off. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. The primary supply voltages define the on-resistance profile, whereas the secondary supply voltages define the voltage level at which the overvoltage protection engages. When no power ...
