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 ...

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, ...

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, ...

本文要分享的是Mullard FJH291/7403N，它是一颗Quadruple 4-input NAND gate with open collector output transistor. （四路4输入NAND门，开漏输出晶体管）是一种数字逻辑集成电路，具有四个4输入NAND门，并且输出采用了开漏（open collector）输出结构。 1-完整芯片的dieshot高清图片 对 ...
