TCA9617B:TCA9617B

Part Number: TCA9617B
Other Parts Discussed in Thread: TXU0101, SN74LVC1G17

Tool/software:

According to the datasheet, TCA9617B is a CMOS integrated circuit and does not involve IIC protocol analysis. If I directly provide a 50Hz square wave (not an IIC waveform) on one end of TCA9617B, will the other end output an equivalent 50Hz square wave? Could you please help answer this? Thank you.

    Yes.

    I²C uses open-drain signals, so the speed of rising edges depends on the pull-up resistors. And the TCA9617B does not support more than 1 MHz. But inside these constraints, it will buffer and repeat any digital signal.

    (For a single-channel, unidirectional signal, better use the TXU0101, or a buffer like the SN74LVC1G17 if you do not need level shifting.)
