  • SN74CB3T3257: SN74CB3T3257 3.3V to 5V drive

    TI Thinks Resolved
    Part Number: SN74CB3T3257 I understand the CB3T family can do 5V to 3.3V level shifter as well as 2:1 mux. But when we up drive 3.3V to 5V, do we just add pullup on the 5V side? B1 -3.3V input B2 - 5V input A - 5V output <= Need pullup? Thanks, K…

  • SN74CB3T3257: length limit

    TI Thinks Resolved
    Part Number: SN74CB3T3257 Other Parts Discussed in Thread: TMUX1574 , , SN74CBTLV3257 Hi Team, My customer wants use this part for SPI signal transmission and they want to know this device output length limit. from my understanding we can calculate length…

  • SN74CB3T3257: Switch high voltage drop

    Part Number: SN74CB3T3257 Is SN74CB3T3257PWR a fully bi-directional switch? Is the switch electrical behavior identical on both directions, A ports to B ports and B ports to A ports? I am asking this because I performed the following test: I placed 3V…

  • SN74CB3T3257: Similar Switch with Translate Up from 2.5V to 3.3V

    Resolved
    Part Number: SN74CB3T3257 Other Parts Discussed in Thread: SN74AVC8T245 , SN74CB3Q3257 The SN74CB3T3257 can translate from 3.3V to 2.5V is there a multiplexer with similar delay propagation (under 1ns max) that can translate from 2.5V to 3.3V???

  • Ron value for SN74CB3T3257 at Vi greater than 0V

    Hi there, The datasheet specifies the Ron value for 2.3V VCC and 3V VCC with the Vi set to 0V. It doesn't show what the Ron would be with Vi at various values such as 1.7V or 2.4V. Unlike the CB3Q which have a pretty flat Ron response, the CB3T is…

  • RE: TMUX136: I3C solution request.

    Hi Tyler, Does level shift (SN74CB3T3257) can support I3C push pull mode? Regards, Mark

  • RE: TS3A27518E-Q1: Whether could achieve logic and also achieve level shift at the same time

    Only CB3T switches support level shifting. The only CB3T 2:1 switch is the SN74CB3T3257, and it would require at least 2.5 V.

  • RE: SN3257-Q1: Use of Auto-Qualified Mux for Mux function and Voltage Shifting to selectively connect uC and hardware safety circuit, 3,3V input to 5V output

    Hi John, So the SN3257-Q1 does not have any capability to level shift the inputs at all and is just a passive 2:1x4 channel switch (inputs ~= outputs). Unfortunately, we do not have any automotive qualified level shifting multiplexers available at the…
