"Strange" modifies the verb "acting" so the adverb "strangely" is required.

Chip in Question: ON Semiconductor - MC14504B
Datasheet Link: https://www.onsemi.com/pdf/datasheet/mc14504b-d.pdf
Issue at Hand:
I am intending to use this chip alongside Arduino Mega 2560. When I bring Arduino pin High(5VDC) I was opening a relay. I had to change the relay to one that opens at around 7VDC. Because of this I am using the MC14504B to step up the voltage and open relay when set to high.

My understanding of the chip is that when you enter 5VDC into VCC and 9VDC into VDD, then apply a 5VDC(HIGH or 1) to one of the eight "IN" pins, the corresponding "OUT" pin should then be brought to HIGH or 1, at voltage applied to VDD.

In practice this is not the behavior I am experiencing. Measurements were made with Calibrated Keysight 3458A. Please see schematic and notes below. enter image description here

I am not understanding why when I bring FIN to match VCC, why I am not getting the voltage at VDD off pin FOUT as described. I am using all the channels on this chip, but for ease of understanding made a sketch of the problem at hand.

I am using a total of 3 of these chips for (8x3) 24 Channels.

Can someone help me understand what I am doing wrong. I am fairly new and self taught to electronic engineering.
