Display Decoder
https://www.electronics-lab.com/article/display-decoder/
Display Decoder A Display Decoder is a type of Binary Decoder, discussed in the previous article, with the main purpose to drive a display. As such, it is a combinational logic circuit that converts input binary data into a corresponding number of output lines which are connected to a display for displaying information such as […]

This essential logic circuit converts n input signals into 2^n outputs. It’s used for memory addressing, chip selection, and translating formats like BCD to decimal.
The Demultiplexer
https://www.electronics-lab.com/article/the-demultiplexer/
The Demultiplexer The Demultiplexer or DEMUX is a combinational logic circuit that connects one input line to one of the several output lines, one at a time. Like a Multiplexer, the Demultiplexer contains no memory, storage, or feedback. Being a combinational logic circuit, its output is solely dependent on the information present on its input […]
Texas Instruments TXU0202 Voltage-Level Translator
https://www.electronics-lab.com/texas-instruments-txu0202-voltage-level-translator/
Texas Instruments TXU0202 Voltage-Level Translator is a 2-bit, dual-supply non-inverting fixed-direction voltage level translation device. Ax pins are referenced to the VCCA logic level, an OE pin can be referenced to either VCCA or VCCB logic levels, and a Bx pin is referenced to the VCCB logic levels. The A port can accept input voltages […]
Digital Buffer
https://www.electronics-lab.com/article/digital-buffer/
Digital Buffer The digital buffers are used in digital circuits for the amplification of digital signals in order to drive high current loads. Besides current amplification, the digital buffers provide isolation between input and output circuits where output is connected to some high-power load such as a relay, lamp or solenoid, etc. The digital device […]
Building a simple Circuit Probe

Vicente Jiménez has published a new project. It’s a circuit probe that gives an indication when a node is floating or driven logic high or logic low and can also be used as a continuity tester. He writes: Sometimes you need to check one circuit and test some of its nodes. Usually a tester in […]
The DigiRule – a digital ruler
https://www.electronics-lab.com/the-digirule-a-digital-ruler/
Brad has designed a cool binary PCB ruler, The DigiRule: So I made the DigiRule! – The DigiRule is a 15cm (6″) ruler with which is marked in binary digits rather than decimal. It has a number of built in digital functions including: logic gates, flip flops, counters etc. The DigiRule – a digital ruler […]
Logic PCB Business Card

Floyd-Jones designed his own business card using logic circuitry. He writes: The card implements a digital finite-state machine which displays the next character of my last name on a 7-segment display each time the button is pressed. Luckily all 11 characters in my name can be reasonably shown, essentially spelling out FLoyd-JonES. I simulated the […]
