Hello,
I have built a board with a TCA9406 I2C level shifter to change 3.3V I2C to 1.8V I2C. I'm having trouble with a device on the 1.8V side of the level shifter - it won't recognize a low value of 0.4V which is the max value of VOL of the TCA9406 (this device's VIL is close to 0.25V).
Can you recommend a pin-compatible part to the VFSOP package with a lower voltage VOL on the VCCA side?
Thanks,
Ben
