Do you speak GAL? [Peterzieba] does, and has pulled together a collection of documents and tools so that you can too. There’s a dividing line in electronic engineering education, between those who ...

Figure 1 Use a portion of a programmable-logic device or gate array to implement a Schmitt-trigger buffer (a) by adding either two (b) or four external resistors (c). Thanks to its internal hysteresis ...

Ernie Smith is a former contributor to BizTech, an old-school blogger who specializes in side projects, and a tech history nut who researches vintage operating systems for fun. When it comes to major ...

Back in the bad old days, if you needed a little bit of custom logic you would whip out a tiny chip known as a PAL. A Programmable Logic Array is just what it sounds like and is the forerunner of ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

Programmable-logic devices are the fastest growing segment of the logic-device family for two fundamental reasons. Their ever-increasing gate count per device gathers up functions that you might ...
