TXB0104 operation

Other Parts Discussed in Thread: TXB0104, SN74AVC4T774

Hello,

My customer has two questions about the TXB0104 operation.

Q1) When the VCCA voltage is less than 1.2V, how about the OE function operating?

Q2) Is It possible to translate individually at the same time as attach file?

    Hi Naoki,

    For question 1, although VCCA range is from 1.2 to 3.6, Circuit behavior is normal when VCCA is more than 1~1.1 V. Thus, OE function also work if VCCA>1~1.1(VCCB shoul be powered).

    For question 2, the application circuits works. But if PCB trace on I/O is too long, it is better to use SN74AVC4T774 as level-shifter.

    Thanks

    Hi Wei,

    Thank you for your very fast reply.

    I will check my customer's PCB trace and recommend the SN74AVC4T774 if need.

    Thanks
