You accidentally bought the wrong chip and got an inverting

\"You accidentally bought the wrong chip and got an inverting three stale buffer (for example an 741S240) What do you need to do to replicate the operation of a non-inverting three-state buffer? You should select only one answer but m little answers can be correct.\" Add a \"regular\" inverter to the input d the inverting buffet Add a \"regular\" inverter to the output of the inverting buffer Add a permanently enabled averting buffer to the input of the inhering buffer. Add a permanently enabled inverting buffer to the output to the inverting buffer.

Solution

The correct answer is to add regular inverter to the input of the inverting buffer since if we add the inverter at output it will still have an output even when the output of buffer is in high impedance state based on the logic family of the inverter.

However if the inverting three state buffer is at output stage then it can still produce high-impedance state indepent of the input stage inverter.
