SN74AC08DR
The SN74AC08DR, made by Texas Instruments (TI), is basically a quad 2-input AND gate IC—meaning it has four separate “AND gates” built into a single chip, each with two inputs and one output. It’s great for use in digital logic circuits, giving you clear and reliable signal processing.
This chip supports a wide voltage range, from 2V to 6V, offering flexibility for different circuit designs. Plus, it provides fast switching speeds and clean output signals, which significantly reduces noise—a huge advantage in high-speed digital applications.
Because it comes in an SOIC surface-mount package, it’s easy to solder and saves valuable PCB space, making it ideal for compact designs in communication equipment, control systems, and other digital electronics.
In short, if you’re working on an electronic device that demands stable and reliable logic handling, the SN74AC08DR is a practical choice. It’ll simplify your logic control tasks, help streamline your signals, and ensure dependable operation.

SN74AC08D digital logic circuit
The SN74AC08D is a high-speed CMOS quad 2-input AND gate from Texas Instruments, offering four independent AND gates in a single 14-pin SOIC package. Each gate performs the Boolean function Y = A • B in positive logic.
This is a typical OR gate circuit, used for controlling the state (on/off) of an LED.
-
The circuit includes two inputs (Input A and Input B) and one output (Output).
-
An LED is connected between the OR gate output and ground, with a series resistor to limit current and protect the LED.
-
The OR gate outputs a high level (logic 1) if at least one of its inputs is high. It outputs a low level (logic 0) only when both inputs are low.
