Digital Logic Circuit Kit – Pharos University in Alexandria 2026–2027

Product Description

This digital logic circuit kit for Pharos University in Alexandria students is a complete bench set for building and testing logic circuits on a breadboard during the 2026–2027 academic year. It brings together the logic ICs, input switches, indicator LEDs, display, power parts, and basic tools a student needs, so there is no need to piece the list together from different sources.

The core of the kit is a set of 74-series ICs. The 7404 hex inverter, 7408 quad AND gate, 7432 quad OR gate, and 7486 quad XOR gate cover the fundamental gate functions. The 7483 4-bit binary full adder and the 7485 4-bit magnitude comparator extend the kit into arithmetic and comparison circuits, while the 7447 BCD to 7-segment decoder/driver works with the 5161BS common anode displays to turn a binary value into a readable digit.

Working with the kit follows a simple pattern. DIP switches and push buttons act as inputs, letting you set each line to a logic high or low by hand. The ICs process those signals, and the 5mm LEDs or the 7-segment displays show the result. This makes it easy to confirm a truth table, trace how a signal moves through a gate network, or check that an adder produces the right sum. A 5V 2A wall adapter supplies power to the circuits, and the kit also includes a 7805 5V positive regulator and a DC female wire connector for anyone who wants to build their own regulated 5V stage.

The quantities are generous for a student kit. With 24 LEDs, 12 resistors of 330 Ohm for current limiting, two 8-way DIP switches, six 4-way DIP switches, and eight push buttons, multi-bit circuits such as a 4-bit adder or comparator can be wired without running short of inputs or indicators. Several of each logic IC are included, so you can combine gates into larger designs. A 840-point breadboard with split power rails gives enough room for the layout, and the 140-piece jumper wire kit and a wire cutter cover the wiring and trimming.

Typical buyers are students preparing lab work and assignments, and anyone practicing combinational logic at home who wants a parts set that matches the course list instead of guessing at substitutes. Everything arrives in one package, which also helps when several students need identical sets.
