  • SN74LVC541A: Is 5V on Vcc ok for part?

    Resolved
    Part Number: SN74LVC541A Other Parts Discussed in Thread: SN74AHCT541 Is 5V ok to be applied to pin 20 Vcc of SN74LVC541APWR? The recommended is 3.3V, but I see the max rating is 6.5V. So does that mean 5V Vcc is ok? That means the output will be 5V with…

  • RE: TXB0106: output(A->B) low level does not reach to 0V

    Resolved
    To convert 5 V to 3.3 V, you can use any buffer with overvoltage-tolerant inputs, such as the SN74AHC367. To convert 3.3 V to 5 V, you can use any buffer with TTL-compatible inputs, such as the SN74AHCT367. (8-bit devices like the SN74AHC541/SN74AHCT541…

  • RE: SN74HCS244-Q1: "Convert" digital 3.3V to 5V

    Resolved
    TTL-compatible CMOS inputs are designed to have practically no shoot-through current for 3.3 V signals: For 7 channels, I'd suggest the SN74AHCT244 or SN74AHCT541.

  • SN74F541: Logic compatibility with XC7A200T

    TI Thinks Resolved
    Part Number: SN74F541 Other Parts Discussed in Thread: SN74AHCT541 Hello Guys, Good day. Need your help to confirm logic compatibility between these two parts: XC7A200T-2FBG676C-LVCMOS (Driver) (VOH&VOL: 2.9 & 0.4) and SN74F541DW-LVCMOS (Receiver) (VIH&VIL…

  • RE: SN74AHCT02： Input TrTf

    Resolved
    I would recommend 2× SN74HCS02 at 3.3 V and one SN74AHCT541 at 5 V (or any other 8-channel TTL-compatible buffer ).

  • RE: TXB0108: waveform of 5V level-up output

    Resolved
    Yes, a load that is too large looks like this. If the signals are unidirectional, a direction-controlled translator like the SN74LVC8T245 will work much better. (AXC does not go above 3.3 V.) But for 3.3 V → 5 V translation, you could simply use a buffer…

  • SN74LVCC3245A: LVTTL to TTL level shifter

    TI Thinks Resolved
    Part Number: SN74LVCC3245A Other Parts Discussed in Thread: SN74LVC8T245 , SN74AHCT541 Hi team, My customer looks for LVTTL to TTL level shifter (greater than 4bit is preferable). For now, I'm promoting SN74LVCC3245A. Could you please propose any successor…

  • RE: TXS0108E: TXS0108E - not working as expected.

    Resolved
    That 50 mA value is the allowed current flowing through the closed switch, which happens only for the input at GND, and relies on the drive strength of the external device. A current of 0.33 mA through the 10 kΩ pull-up resistor would result in a voltage…
