CD74HC393: RFQ SUPPORT

ALESSIA STEFANO

Part Number: CD74HC393

What are the differences between CD74HC393MG4 and CD74HC393M96?

Why is the component marked 38Z1TCJH393MG3?

Thank you

"M" indicates the SOIC package; "96" is the size of the reel; "G4" has no meaning nowadays (see [FAQ] Why does a logic device's part number have an E4/G4 suffix?). The chips are identical.

The marking for chips sold now is "HC393M". I'd guess you have an older one.

Thank you very much.

What does it mean instead " 38Z1TCJ "? Does it indicate the production batch?

The datasheet says:

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
