    In the early days of personal computers, incorporation of one or two (or more) RS-232 serial ports as general purpose I/O adaptors was common practice. Recently, this “vintage” standard has been largely replaced (after all, it is 64 ...

    The 0- to 20-mA current loop is a reliable means of data communication in industrial applications. These circuits use a precision shunt in the receiver to convert the current signal into a voltage signal. Accidentally connecting the precision ...

    It is advantageous to know if there is a valid signal on a differential signal bus. This Design Idea detects differential data transmission and reports a loss of signal (LOS) to a microcontroller or other monitoring device. The circuit of Figure 1 ...

    The popular I 2 C communication standard manages to perform flexible serial I/O with just a super simple two pin bus: SCL and SDA. It accomplishes this trick with bidirectional timing and data flow. Bidirectional flow is good at saving pins but due ...

    I 2 C is a popular bidirectional serial communications bus having a clock and a data line. Both line’s drivers consist of an open drain ground-referenced N-channel MOSFET with a pullup resistor connected to a supply ranging from 1.8 V to 5 V. ...

    It’s common for I 2 C systems to have both standard and fast devices on the same bus. For I 2 C systems, the speed and power consumption both depend on the values of pullup resistors: the values of them should be low enough to secure the fast ...
