Does anybody know what 74HB139 is?
It might be SN74HB139, 54HB139 or something like this. 16 pin TSSOP, made by Texas Instruments, marked as follows: HB139 (TI Logo)97K KDT6 I'm 100% sure it is good old 74xx139 but what the heck is "HB" ? Google brings only a bunch of good chinese guys that have everything in stock, whatever it's called, but not even a single piece of information... It _IS_ "HB", not "HC". There are several of those and all are exactly the same. Any info on HB logic family? --- ************************************************** **************** * KSI@home KOI8 Net The impossible we do immediately. * * Las Vegas NV, USA Miracles require 24-hour notice. * ************************************************** **************** ** Posted from http://www.teranews.com ** |
