Other Parts Discussed in Thread: TXU0304-Q1, TXU0104-Q1, TXU0204-Q1, SN74AXC4T245-Q1, SN74AXC4T774-Q1

Hi, Support Team

as below diagram sky blue block, limited signal path as single direction. 

Could recommend for level shifter the directions signal-only(or controllable) for Automotive parts.

if any, Please advise me.


Best regards,


  • The TXU0104-Q1 is P2P, if the direction is A to B. (For other combinations of directions, see the TXU0204-Q1/TXU0304-Q1.)

    For selectable direction, see the SN74AXC4T774-Q1 (one direction per channel) or SN74AXC4T245-Q1 (directions in groups of two).

  • Hi, Clemens

    I have fuel questions need check as below.

    1. Is SN74AXC4T774-Q1 and SN74AXC4T245-Q1 design different between those?
    a. SN74AXC4T774-Q1 is design for more direction-control flexible?
    b. SN74AXC4T245-Q1 is design for more output enable flexible?
    c. Pre-channel frontend design is push-pull or Schmitt?

    2. TXU0104-Q1, TXU0204-Q1, TXU0304-Q1 those different is only in pin(s) direction?

    if any suggestion, Please advise me.


    Best regards,
