SN54AC14: Question regarding different Inverter Schmitt Triggers - RUAG Space

Part Number: SN54AC14
Other Parts Discussed in Thread: , SN74AC14-Q1


My name is Leonard Andersson and I'm a component Engineer at RUAG Space, working for the New Space department where we are focused on automotive and COTS components for missions that are closer to earth's surface.

My questions are:

Is it the same chip being used in SN54AC14 as in SN54AC14-SP?

What is the difference between SN74AC14-Q1 and SN54AC14, except the automotive vs military rating? Is it different chips in 54 vs 74?

Best Regards,

Leonard Andersson
