When starting a new electronics project today, one of the first things that we tend to do is pick the integrated circuits that make up the core of the design. This can be anything from a ...

CMOS opened the door for many if not most of the properties needed for today’s highly integrated circuits and low power portable and mobile devices. This really couldn’t happen until the speeds and ...

The logic on-off function allows the user to shut off the converter’s output using a simple TTL logic signal or mechanical switch, and avoids having to turn off the DC input bus. This feature is ...

You can’t leave unused inputs floating, but you might not want to connect them to a power or ground rail either. Digital engineers learned long ago that they should not leave unused inputs unconnected ...

I saw a request about how to interface an audio signal with a microcontroller for logic level switching. I started thinking a lot about it and found some quick fixes. This post has my ramblings about ...

This is a TTL logic probe which, instead of the usual LED to indicate the logic states, uses a seven-segment Minitron or LED display to indicate `H` for a high or `1` state and ` L` for a low or `O` ...

Efficient Power Conversions (EPC) has released a new high-performing gate driver and low-voltage differential signaling (LVDS) logic level input in a single chip for time-of-flight lidar systems used ...

Confused? Join the club. It wouldn't be confusing, though, if I hadn't started with the ancient history of RTL logic. Most of today's designers have never seen or used an RTL gate anyhow, so they aren ...

The GBS-8200 video upscaler is advertised as being able to convert CGA/EGA video to VGA, but it can't handle either without further modification. The missing pieces for being able to feed CGA and EGA ...
