#157262 - Can you give an example? Responding to: ???'s previous message |
Neil Kurzman said: Actually, I think it started with 'i' for Intel, since it was a good 10 years before Philips got hold of it. The original 8051 Started with P for Plastic. ... EX: the 4066 comes in a 5 volt and a 12 volt version ( not all mfg). It is all in the letters and manufactures. ( Mfg A is out of stock on the the part can we use Mfg B) I'm aware that there is a 74HC4066, just as there are numerous outher logical equivalents among the 74HC series, but that's not a CA4066 or 14066 equivalent. The 4000-series CMOS, patterned after the CA4000-series, operates at 3.5 to 15 volts, IIRC, while the few 74HC versions of those parts only operate within 10% of the 5-volt supply as intended for 74HC-family devices. Confusion runs rampant among those devices and their spec's. Using 'em without first thoroughly looking at the datasheet, you're asking for trouble. RE |
