Phil said:Those were nice parts. I still have some left too...iirc they're in the
1989 data book. I'll look them up and see if I can post the
datasheet--basically they were the LF3xx series with the current limit
resistor pinned out separately, so you could use higher current at lower
supply voltages.
National did some *weird* stuff in 1988--they came out with about 20 new
*hybrid* designs, like the LH4009 buffer. Of course, those lasted about
2 years and went the way of the dodo. I still have some.
They also did some not-so-nice stuff. Brought LH0063 and 0033 buffers to
market, excellent parts, used by ATE folks all around the globe, then
sent out the funeral notice. Now there is the occasional fist fight
among obsolete-parts dealers if a stash shows up somewhere.
