Most of the parts we use operate at 3.3volts, but we still run into a lot of old 5volt stuff, and an occasional 2.5volt or 1.8volt part. This post explains how to use the Bus Pirate’s open collector ...

It is common practice to use digital open-collector outputs for control units in industrial applications. Using these outputs, you can switch loads, such as relays, lamps, solenoids, and heaters. One ...

At the heart of a transceiver is usually a phase-locked-loop (PLL) synthesizer, which delivers a signal to downstream components such as mixers, filters and power amplifiers. At higher frequencies, ...

The SeaI/O-530 and SeaI/O-540 DAQ Modules integrate open-collector outputs and optically isolated inputs for distributed control. Ordering options allow control from a host device via wireless, ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...
