  • SN74CBT3384A: Level shifter or switch

    Resolved
    Part Number: SN74CBT3384A Hi, In my case, I need very minimal propagation delay. My application is 5V <-> 3.3V bi-directional bus. Normal level shifters (ex: LVC, AXC families) specifies at least 4ns delay. switches like CBT offers <0.5ns delay. can I…

  • SN74CBT3384A: Audible signal through the switch during off-state?

    Part Number: SN74CBT3384A I've designed a component video + audio switch using the SN74CBT3384ADWR. Unfortunately, while either switch / both switches are in the 'off' state (~OE pin high) there's a lot of signal bleeding through. If the Luma signal…

  • SN74CBT3384A: Max value for input capacitance

    TI Thinks Resolved
    Part Number: SN74CBT3384A Other Parts Discussed in Thread: TMUX1511 Hi team, Does TI provide max value for input capacitance as referenced value? The datasheet says only typical Ci value 4pF. Best regards, Takeshi Sasaki

  • SN74CBT3384A: Some voltage on Input pins when VCC not powered

    Resolved
    Part Number: SN74CBT3384A Other Parts Discussed in Thread: SN74CBT3384C Hello, I have a question for SN74CBT3384A. Input voltage range of absolute max is defined as just “-0.5V to 7V” without any relation to VCC. Doesn’t it really depend on…

    TI Thinks Resolved
    Part Number: SN74CBT3384A Other Parts Discussed in Thread: SN74CB3Q3384A Hi, Since there is no information of VOH, VOL in the data sheet of SN74CBT3384A, we refer to scdd001b. Application notes (scdd001b) 9-7 (page 355) It has the following description…

  • SN74CBT3384A: CBT vs. CB3T for translating 5V to 3,3V (bi-directional).

    TI Thinks Resolved
    Part Number: SN74CBT3384A Other Parts Discussed in Thread: SN74AVC16T245 Having read several documents like e.g. "CBT-C, CB3T, and CB3Q Signal-Switch Families" I'm still unsure whether to use a CB3T or CBT device for translating bi-drectional…

  • RE: TXB0304: 5-3.3V level converter

    TXB level shifters have extremely weak outputs and cannot be used with pull-up/-down resistors or long traces or cables. The SN74CBT3384A is not obsolete. If you do not want to use it, use another level shifter based on passive switches, like the TXS0104E…

  • RE: SN74CBTD3384DW and HPI on DSP TMS3206713

    Resolved
    Thes part are for very low frequency. If you are running faster than 1Mhz you should use either SN74CB3T3384 wich would require 3.3V Vcc or SN74CBT3384A - SN74CBT3384C with an external diode in series with Vcc. This would be the same type part as CBTD but…

    Although the CBT3384 is not recomended for new designs their improved replacement are available. The replacements are. SN74CBT3384A SN74CBT3384C The C-rev has undershoot protection down to -2.5V. The CBT devices are simply n-channel FET switches so they…
