  • MPC509: Out pin voltage when not powered

    Resolved
    Part Number: MPC509 Hello, Let me confirm the device behavior when +V and –V are not powered. In the datasheet, there is the below description on P11. “If the +15V and/or –15V supply voltage is absent or shorted to ground, the MPC509A and…

  • MPC509: Minimum supply voltage that signal feedthrough doesn't occur

    TI Thinks Resolved
    Part Number: MPC509 Hello, From my previous post, I understand some voltage could output if +V/V- are not powered. Then I have an additional question. How much supply voltage is required to ensure multiplexer work correctly, meaning no signal feedthrough…

  • MPC509: digital input (Ve and Va) over-voltage protection

    TI Thinks Resolved
    Part Number: MPC509 Other Parts Discussed in Thread: MUX36D04 , MUX509 , Hi Team, In the datasheet, max rating spec or over-voltage protection (OVP) spec, we have Va and Ven at Vs(+) = +4V and Vs(-) = -4V At same time, Va and Ven VIH(min) is also…

  • RE: RS422 / RS485 loopback self test

    It would be possible to switch the TX and RX on the logic side. But if you need to test the RS-422 side, then you indeed need a switch that can handle all voltages that might actually appear on the bus. This typically requires a power supply covering…

  • RE: Question about the Analog Multiplexer voltage stand

    Resolved
    Hi Jim, Unfortunately we do not have any load switches which can handle 200V. Because the MPC509 falls under the Internal Signal Switches Applications Support Forum I will move this thread there. Thanks, Alek Kaknevicius

  • RE: Signal Switches - Voltage tolerance

    Hi Anton, In general, the absolute maximum voltages for the outputs will be specified in the datasheet. For example, the dual SPDT TS3A24157 specifies the maximums on the NC and NO outputs on page 2 of the datasheet: Voltages higher than specified…
