Name the 7400 series TTL chip which is a priority encoder. Write its truth table. Ans.
Available IC in 74 series is 74147 that is a priority encoder. Such IC has active low inputs and outputs. The significance of the word priority can be realized from the truth table. For example if 2 and 5 are low, the output will be consequent to 5 that has a higher priority than 2 that is the highest numbered input has priority over lower numbered inputs.
