Logic level shifter

Which ic is suitable for 5V to 3.3V conversion of 8-bit data.

1 Reply

  • Hello Sukumar,
    There are many devices that can do this conversion, and the best choice will depend on several factors.

    Is all the data being transmitted from 5V to 3.3V, or is some transmitting from 3.3V to 5V?

    Do any of the data channels change directions during operation? (and if so, is there an indicator line to control direction?)

    What is the maximum data rate required?

    What is the worst-case parasitic capacitance on the lines?

    How much current can the respective transmitters (3.3V and 5V) source/sink?
