Other Parts Discussed in Thread: SN74LVC2T45
Hello
I want to use TXS0102 to drive WS2812 led strips from an esp32 (and possibly reuse the port for 5V input).
ESP32 is 3.3V and WS2812, although it can work at 3.3V, signal should be at 5v.
I attached a TXS to a test bench, with 3.3V on VCCA and 5V to VCCB. Input is a 3.3v square signal from a function generator and output to scope.
Around 10KHz output signal look fine, but at 800KHz output voltage is too weak.
Why the rise time takes around 4µs ?
CH1 is input, CH2 is output
Thanks for your help
Nicolas
