hi dear supporting team,
if customer put OE =L, DIR=L, and B port input source set to HI-Z, will A port output be hi-Z as well? if not, what's the status of A-port output will be? tks a lot!
When DIR is L, the B inputs are active and must always be driven to a valid logic voltage (see [FAQ] How does a slow or floating input affect a CMOS device?).
If the B inputs are floating, they read a random value (either low or high), and that value will be output at A.
