Have any of you guys (and gal) ever considered using or used a 4067 for a 16
step sequencer? It's an interesting little bug as it is actually a bank of
analog switches which are addressed by 4 bit data with a common
input/output.
So, you want to pass a low out as true, you ground the common. You want a
high, you connect a high at the common. In that this project I'm cooking up
is going to be gargantuan, I'm going to use line drivers after to boost the
umph for 4 banks, a pulse out, a programmable pulse out AND an LED per tap,
so I'm not all that concerned with it's internal strength as there will be
no fan outs.
any info would be terrific.
thanks,
P
