Tool/software:

Hi team, 

Customer have a requirement for a 8 channel buffer that output=low when N_OE=high instead of hi-Z. Do you have any recommendations? 

Thanks!

    Add pull-down resistors at the outputs.

    If you need high drive strength, use AND gates; in that case, the control signal is high for active, and low for output low. If the control signals needs to have the same polarity as with the '541, add an inverter gate.
