Re: Plastic or ceramic ICs?
For the princely sum of £1.50 apiece I've just acquired a couple of Motorola 4049s which are allegedly mil-spec. The complete designation is "14049A/BEAJC 883 CGG QY 8604U"
I've seen designations such as BEAJC and BCAJC on ICs previously but never understood them. Motorola data books suggest that the "B" is the level of MIL-883 to which the device is qualified and that "EA" is something to do with the packaging but quite what a 4049A is eludes me. I assume it's unbuffered and that 8604 is the date code but can anyone shed further light?
No amount of Googling seems to help, naturally.
