The 74HC00 data sheet warns that inputs must not be allowed to float because this makes the output indeterminate. Now, that in itself is a good reason, but there is more… In my previous column, we ...
In today’s highly competitive semiconductor industry, chip-design companies strive for competitive advantages by optimizing designs for PPA (Power, Performance, Area). Along with the functional logic, ...
It turns out that if you run standard CMOS at 3.3 V, the logic levels are the same as TTL running at 5 V. In my previous column, we took a look at the 74HCT series of CMOS parts with TTL-compatible ...
