Hi,
I always pull high enable & SEL1, and use MCU control SEL2 to open channel B,
but sometimes will let the IC break down, and channel B doesn't work,
Do you have any sugguest? thanks!

Hi Ray,
can you please provide more detailed information in which situation exactly (Supply voltage, input voltages at the control pins) the problem occurs? Please also include information about the NAND-WPZ signal characteristics.
Best regards
Cevin
Hi Ray,
Switching SEL1 and SEL2 while EN is high shouldn't be a problem, could you elaborate on the problem you are facing?
