Frequently Asked Questions
Which logic designs benefit from CD74HC147M96E4 priority encoding?
CD74HC147M96E4 converts 9 active-low inputs into a 4-bit coded output, making it useful where several request lines must be reduced before controller processing.
How should designers budget timing and loading for this HC encoder?
The device supports a 2 V to 6 V supply range, a 50 pF load condition, and propagation delay as low as 12 ns at 6 V.
What package-level checks matter before approving CD74HC147M96E4 for production?
Review the SOIC-family drawing and assembly footprint because the JESD-30 package code indicates a 16-pin plastic small-outline format for surface-mount manufacturing.
