Multiplexer/accent problem?

Multiplexer/accent problem?

Postby njosnari » Feb 13th, '18, 11:58

I originally ordered this 8ch multiplexer from mouser: ... 5-CD4051BE

Of the 2, one was not functioning properly. So I ordered this as a replacement from farnell: ... dp/1106109

I have now gone through 7 of them over 2 orders, and none work properly! Its like they have a different pin out, as the voltages read differently across the legs of the working IC vs all the non working ICs. Are these not the same CD4051BE? Have I been given a bad batch and notify Farnell?
