Logic Diagram
Description
The ATV750(L) is 100% more powerful than most other programmable logic devices
in 24-pin packages. Increased product terms, sum terms, and flip-flops translate into
more usable gates.
Each of the ATV750(L)鈥檚 twenty-two logic pins can be used as an input. Ten of these
can be used as input, output, or bi-directional I/O pins. All twenty flip-flops can be fed
back into the array independently. This flexibility allows burying all of the sum terms
and flip-flops.
There are 171 product terms available. A variable format is used to assign between
four and eight product terms per sum term. There are two sum terms per output, pro-
viding added flexibility.
