**Chip in Question:** ON Semiconductor - MC14504B<br> **Datasheet Link:** https://www.onsemi.com/pdf/datasheet/mc14504b-d.pdf <br> **Issue at Hand:**<br> 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. <br><br> 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.<br> 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][1]][1] [1]: https://i.sstatic.net/Y32Iw.png I am not understanding why when I bring FIN to match VCC, why I am not getting the voltage at VDD 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.
