54-series chip?

[pc88]

I have a bunch of 54SC374 chips. I suppose they are equivalent to 74374 - is that right?

Does anyone know what the electrical characteristics of 54-series chips are?

Yes, but the 54 denotes military specs, even better than the 74xxx.

The primary difference is that the 54 series has a greater operating temperature range than the 74 series.

I seem to recall that the 54 series as well as having wider temperature ratings also were required to have hermetically sealed packaging? I think the latter spec is what made them more expensive.
