SN54AC74-SP: space grade logic AND and D-flipflop with TID radiation data

Hello,

I’m looking at your space grade logic line for AND gates and D-flip-flops but I don’t see radiation TID numbers for them. Do you know if you have any that are rated for 100krad?

Which logic devices have rad data available?

THanks,

Adam

As shown on pages 23/24 of ti.com/spaceguide, there are no AND gates or D-type flip-flops that have been radiation tested.

Hey Adam,

Clemens is correct. The only logic gates we currently have with radiation testing are the:

SN54AC14-SP Hex Schmitt-trigger inverters - QMLV TID 50 krad

SN54AC00-SP Quad NAND gates - QMLV-RHA TID 100 krad, Max SEL 86 MeV-cm^2/mg

SN54AC02-SP Quad NOR gates - QMLV TID 50 krad

SN54LVC646A-SP Octal bus transceiver and register - QMLV TID 50 krad
