what is "strapping"

Apr 14, 2005 6 Replies

I am reading the 80C188XL document and it reads "Pins specified as 'pulled high' or 'pulled low' can be strapped instead. using pull-up or pull-down resistors instead of strapping makes design changes easier and less costly." Does the word "strapping" mean that the pins are connected directly to vcc or vss without resistors, or does it mean that pull-up or pull-down pins are grouped, and connected to vcc or vss with a single resistor?



Thanks

"Strapping" is the word English gentlemen used to use to describe the kind of girls drawn by Robert Crumb.

Or what the teacher or vice principal used to do to bad boys.

I thought that was steatopygous ;)

Careful with the attributions, plesae, I didn't write that. But seriously, "strapping" has a kind of old-fashioned sound to it for modern use in electronics- an 8 mil trace in 0.5 oz copper isn't much of a "strap".

Sorry. I'm trying to get my head around a new newsreader and I've been spazzing out rather regularly.
