Does an Arduino Uno Mega Shield SD Card ICSP SPI Exists Already?

Hi Peter,
This is not working in my scenario for some reason. Can you see what is wrong?

I ordered this part - https://www.mouser.com/ProductDetail/595-SN74AHC125NE4

Here is my schematic -

The pins are the bottom represent the Arduino UNO pinouts… Top left is CS, Pin 10. Bottom is 3.3 V. Just noticed I am missing the ground symbol but everything is grounded.

UPDATE: I have separated the VCC input on the chip (now goes to +5) and sd card reader (stays at 3,3).
Before, both were being powered from the 3.3.

The result is no change; it still doesn’t work.
