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 ...
Transistor-transistor-logic or TTL parts have been around for a long time and now and then, I still seem to run across this or that “thing” where they've been designed in, not necessarily in the ...
The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...
You can’t leave unused inputs floating, but you might not want to connect them to a power or ground rail either. Digital engineers learned long ago that they should not leave unused inputs unconnected ...
Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...
EPC has announced a laser driver that integrates a 40V 10A GaN power switch with a differential input gate driver. Called EPC21603, its inputs are LVDS (low-voltage differential signalling) compatible ...
