  • TMUX1574: spec check

    TI Thinks Resolved
    Part Number: TMUX1574 Hi A customer has a question. TMUX1574PWR was previously used for SPI 1.8V. Now if it needs to be changed to 3.3V (VDD, EN, SEL are also changed to 3.3V), can it be used? If not, which one do you recommend? Thanks.

  • TMUX1574: Pull up resistors on SPI lines with Mux

    TI Thinks Resolved
    Part Number: TMUX1574 When using TMUX1574 to connect SPI from Microcontroller to two devices are pull-up resistors required on the SPI signals on each device? If there are no pull up resistors then the SPI signals to the un-selected device will be floating…

  • TMUX1574: Need Clarification on VIH Specs for Signal Integrity Checks with 1.8V Logic Switch

    Resolved
    Part Number: TMUX1574 Dear Texas Team, I've referenced the "7.5 Electrical Characteristics" section of the datasheet for the Switch with 1.8 V Logic "TMUX1574DYYR" and found that it specifies a maximum High Level Input Voltage (VIH) of 5.5V. However,…

  • TMUX1574: max on resistance

    Resolved
    Part Number: TMUX1574 Other Parts Discussed in Thread: TS3A44159 Hi, Could you tell me what is the maximum value of On resistance when VDD=3.3V and VS=1.8V or 3V? I think Figure 3 shows the Typ value, so I would like a graph of the maximum value. Best…

  • TMUX1574: Can the work reliably with 1.2V Vih at the select pin?

    Resolved
    Part Number: TMUX1574 According to the TMUX1574 data sheet, the Vih (Input logic high) is between 1.2 to 5.5V. I have a SPDT switch connected to the SEL pin that switches between 0 to 1.2V, would the TMUX1574 work reliably? The 1.8V logic I/O supposed has…

  • TMUX1574: TMUX1574 - Switching between two sim cards. Baseband provides power to both sim card, can mux handle pull down for floating signal pins?

    TI Thinks Resolved
    Part Number: TMUX1574 I'm considering using TMUX1574 to switch between two sim cards just like the illustration posted below. The GSM modem provides power to the SIM_VCC so both sim connectors will always be powered even when the mux is switched off…

  • TMUX1574: Missing Protection diodes on analog input

    TI Thinks Resolved
    Part Number: TMUX1574 Other Parts Discussed in Thread: SN74LV4052A I have been looking at analog muxes 2:1 and 4:1 for some time, the TMUX1574 finally came up as what seems the perfect choice for 2:1: low capacitance, low leakage, ultra small package…

  • TMUX1574: I2C mux

    TI Thinks Resolved
    Part Number: TMUX1574 Hi team, Customer would like to use TMUX1574 as a mux for 2 slave device, do they need to get pull up resistor as both side of TMUX1574? Thanks and Best Regards, Will
