I remember the "Fast and Damn Fast Buffer Amp" data sheet. LH0036? I may
not be remembering the correct part number. I used to have a copy of
that data sheet, as well as another that was labeled "DC to Daylight" on
the data sheet.

Hi Doug -
Wow. Wonder how many on here remember or know about National's "Damn
Fast" line, HI. I used them all the time, and, still have a few. 73 -

In the 1984 databook (Blue cover with the yellowing fragile newsprint
pages) and in the 1975 databook (yellow and green cover, nice quality
paper). LH0033 and LH0063 are the Fast and Damn Fast buffer amplifiers.
In this context the data sheet says 6000V/microsecond. With +/- 10V
into a 50 ohm load (although you only get 2400 V/us there)
Last two pages in the 84 book are just blank. Last page in the 75 book
is a description of MIL-STD-883B
Interesting parts.. They aren't kidding when they say you need good
power supply bypassing and decoupling.(a comment that is in the 84 book
but not the 75 version) I'm trying to remember what I was using them
for: driving a YIG tuning coil in a phase locked loop, I think, but it
might have been driving a fast RF switch.
Interesting parts back then.. Does anyone still make or use a LM746
"chroma demodulator" (other than as a replacement part) or any of the
other very purpose specific parts for parts of a TV? (like LM1845 signal
processing, etc.)
