These ever-dropping logic voltages still must drive solenoids, twisted-pair wiring, and discrete-semiconductor-power stages, so they require external interface circuits. You need to understand these ...

Often, it becomes necessary to interface an existing or new 5V AVR / PIC / MCU project to new devices that use 3.3V logic, like memory cards, sim cards, etc. Described here is a circuit that converts ...

In a hard-to-articulate way, it’s somewhat comforting to know that even in our world of highly integrated, multifunction ...

The design community has a love/hate relationship with interface logic. Many designers would like to see it incorporated in ASICs or replaced by some type of programmable gate array at the start ...

Interfacing to this common caliper model is ... a 3D printed connector that makes mating to the pads much more stable and reliable, a simple interface circuit for translating the logic ...

We all use 74 logic in our projects as general purpose logic interfacing glue. These chips have become as ubiquitous as a general-purpose op-amp, or even as passive components. In most cases we&#82… ...
