Analog Devices (DS2408S+) Addressable Switch, 2.8 V to 5.25 V, NSOIC-16

Addressable Switch, 2.8 V to 5.25 V, NSOIC-16Product OverviewThe DS2408S+ is a 1-wire, 8-channel addressable switch in 16 pin NSOIC package.This bidirectional port expander can be powered and operated from singlecommunication line. The programmable I/O 1-wire chip (PIO) outputs areconfigured as open-drain and provide maximum on-resistance of 100 ohm. A robustPIO channel access communication protocol ensures that PIO output setting changeis error free. A data valid strobe output can be used to latch PIO logic statesinto external circuitry such as DAC or microcontroller data bus. The DS2408operation is controlled over single conductor 1-wire bus. Device communicationfollows the standard Dallas Semiconductor 1-wire protocol. Each DS2408 has itsown unalterable and unique 64bit ROM registration number that is factory laseredinto the chip. The registration number provides unique identification and isused to address the device in a multidrop 1-wire net environment.1-wire pull-up voltage range from 2.8V to 5.25VOperating temperature range from -40°C to 85°CControls eight independent I/O port pins from single micro port pinOff resistance of 10MohmMultiple DS2408 devices can reside on common 1-wire bus and can operateindependently of each otherFull scale range for each DAC determined by external resistorsMinimalist 1-wire interface lowers cost and interface complexitySupports 1-wire conditional search command with response controlled byprogrammable PIO conditionsCommunicates to host with single digital signal at 15.3Kbps or 100KbpsStandby supply current of 1µAApplicationsSignal Processing, IndustrialProduct InformationIC Function: Addressable SwitchSupply Voltage Min: 2.8VSupply Voltage Max: 5.25VIC Package Type: NSOICNo. of Pins: 16PinsOperating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -MSL: MSL 1 - Unlimited
