Lessons In Electric CircuitsVolume 4, chapter 3: However, the presence of those extra switches and LEDs make it 4011bs convenient to expand the circuit and help make the circuit layout both clean and compact. It is highly recommended that you have a datasheet for the chip available when you build your circuit.

Practical Electronics/IC/4011

Shown here is my own rendition of what any datasheet shows:. Digital logic circuitry does not make use of split power supplies as op-amps do.

Like op-amp circuits, though, ground is still the xatasheet point of reference for all voltage measurements. Note how all inputs of the unused gates inside the chip are connected either to V DD or ground. This is not a mistake, but an act of intentional design. Who cares what signals they receive, if we are not doing anything with their outputs?

At worst, this could lead to damage of the chip. At best it means excessive power consumption.

In the breadboard illustration, I show all the top inputs connected to V DDand daasheet the bottom inputs of the unused gates connected to ground. This was done merely because those power supply rail holes were closer and did not require long jumper wires!

Basic Gate Function

Please note that none of the unused gate outputs have been connected to V DD or ground, and for good reason! Instead, its upper P-channel output transistor would be turned on in vain, sourcing maximum current to a nonexistent load.

This would very likely damage the gate! This way, the input will not be susceptible to stray static voltages. Even if you already know what a NAND gate truth table looks like, this is a good exercise in experimentation: Draw a truth table on a piece of paper like this:. As you can imagine, this breadboard circuit is not limited to testing NAND gates. Any gate type may be tested with two switches, two pulldown resistors, and an LED to indicate output status.

An improvement you might want to make to this circuit is to assign a couple of LEDs to indicate input status, in addition to the one LED assigned to indicate 4011ge output. This makes operation a little more interesting to observe, and has the further benefit of indicating if a switch fails to close or open by showing the true input signal to the gate, rather than forcing you to infer input status from switch position:.
