CD4069UB

I am having an issue with a build and I just noticed that I used a CD4069UBE IC when it called for a CD4069UB. Can one use these interchangeably?

Both the CD4049UB and CD4049UBE are 'unbuffered' hex inverters. They should be interchangeable. The CD4049B is 'buffered'.

Both the CD4049UB and CD4049UBE are 'unbuffered' hex inverters. They should be interchangeable. The CD4049B is 'buffered' and does NOT invert the signal.

Thanks for your help.

I don't know that I've ever seen a buffered CD4049. In any case a CD4049 is by definition a hex inverter. Buffered or not, it inverts. Perhaps you're thinking of the CD4050.

I re-examined the datasheet and you're right. TI shows the 4049 next to a 4050 and at a quick glance, I assumed they were just the buffered and unbuffered versions - when in fact it was a 4049 compared to a 4050. I've corrected my original comment. Thanks for the head's up.
