Hello all.
Are there any recommendations for or against any of the 4000 series manufacturers (Fairchild, ON, Texas, Philips, ST) ?
Philips is consistently expensive and Fairchild is consistently cheap. Where are those manufactured ?
Hello Andre,
Besides price there are also huge differences in specsmanship and customer support. Huge. Other companies seem to be unable to create a useful web site, making it hard to get any information.
It also depends on what you want to do. If you are planning some unorthodox circuits like I often do then very detailed specifications are absolutely critical. A scanned copy of an old data book isn't always good enough.
Regards, Joerg
Some chips have the country of manufacture in the dimple on the chip.
Back in 1980 when I worked for a test equipment co, they had restrictions on some CMOS chips. But that was because of the very high demand that caused the distributors to sell poor quality components.
