  • SN74LV4051A-Q1: Ground pin inquiry

    Resolved
    Part Number: SN74LV4051A-Q1 Hello, I'm trying to use this part as an alternative to another TI mux that is not in stock. The pinout is the same except that the other TI mux has pin 7 NC, whereas here it is ground. Are the pin 7 and pin 8 ground internally…

  • SN74LV4051A-Q1: Mux Output Issue

    Resolved
    Part Number: SN74LV4051A-Q1 We have implemented the SN74LV4051 Mux for our data acquisition setup. During testing, it was observed that when the channel output configuration is changed, the mux gives an erroneous output and copies the data of channel…

  • SN74LV4051A-Q1: Short to battery issue, when sampling inputs multiple inputs appear to be shorted

    TI Thinks Resolved
    Part Number: SN74LV4051A-Q1 E2E, Can the SN74LV4051-Q1 distinguish inputs shorted to battery? I have an issue where if one input was shorted to battery, all the inputs appeared shorted to battery when sampled. Thank you, Adam

  • SN74LV4051A-Q1: I/O Pin Capacitances (for pins Y1:Y7)

    TI Thinks Resolved
    Part Number: SN74LV4051A-Q1 My customer is trying to understand input pin capacitance of this device (specifically for pins Y1, Y2, Y4, Y5, Y6 and Y7) assuming the switch is not closed to the COM port. I don’t see a good drawing for the defined capacitance…
