Tag: Type of logic gates

Digital logic gate circuits are manufactured as integrated circuits: all the constituent transistors and resistors...

Logic gate circuits are designed to input and output only two types of signals: “high” (1) and “low” (0), as...

NAND and NOR gates possess a special property: they are universal. That is, given enough gates, either type of gate is...

It is sometimes desirable to have a logic gate that provides both inverted and non-inverted outputs. For example, a...

Up until this point, our analysis of transistor logic circuits has been limited to the TTL design paradigm, whereby...

Let’s examine the following TTL circuit and analyze its operation: Transistors Q1 and Q2 are both arranged in the...

Suppose we altered our basic open-collector inverter circuit, adding a second input terminal just like the first: This...

The Use of Logic Gate Inverters and buffers exhaust the possibilities for single-input gate circuits. What more can be...

If we were to connect two inverter gates together so that the output of one fed into the input of another, the two...

The single-transistor inverter circuit illustrated earlier is actually too crude to be of practical use as a gate. Real...

While the binary numeration system is an interesting mathematical abstraction, we haven’t yet seen its practical...
