i need to understand the working of this chip but all the datasheets i find including from TI themselves are very vague and do no explain anything. all the versions i have found are identicle. is there any more info on this IC around ?

Hello,

It's a dual monostable multivibrator, what more do you need to know?.

yea well what frequenzy can it work up to - what values of R and C do i use I just want practical info on it

It's NOT an oscillator, so maximum frequency doesn't really apply - the datasheet gives the formula for calculating the output pulse width, and also gives a graph (figure 9) showing different value capacitors.

Everything you need to know is right there in the datasheet.

ok but the quality of the scan is real crap

Is this Scan Better?
Its out of my Data Book and Photographed with a camera.

Merry Christmas....Gary
