  1. Digital Maxim MAX1658 MAX5400 MAX7301
    Steve Hageman EDN To test products in my R D lab, I build many universal data-acquisition systems that connect to a PC or another controller through RS-232 links or LANs. These small systems typically include multiple ADC, DAC, and digital-I/O ...

  2. Santosh Bhandarkar EDN A simple and inexpensive electronic circuit uses a low-cost pushbutton switch to toggle the electrical power on and off. The circuit replaces a more costly and bulky push-push mechanical switch. The pushbutton switch triggers ...

  3. Digital Nexperia 74LVC2G241 74LVC2G07
    Bob Marshall EDN In new mixed-voltage systems, it is often necessary to level-shift a control signal from a high level to a low level. An open-drain device, such as the 74LVC2G07 , easily performs this shift. However, when a bidirectional signal ...

  4. Michael Whybray EDN Most desk fans I have come across have three speeds: Full Speed, Almost Full Speed, and Off useless if you want just a gentle air movement, and far too noisy if you are trying to get to sleep (in your bedroom of course, not at ...

  1. Digital Fairchild NC7SZ57 NC7SZ58
    Glen Chenier EDN You can assemble a pulse-generation circuit from a simple Schmitt-input AND gate plus a resistor-capacitor timing network. However, if you need a logic function that's not a standard catalog item, you need a Schmitt-input gate ...

  4. Supply Application Notes Digital Analog Devices AD7621 AD7622 AD7623 AD7641 AD7643 AD7654 AD7794
    Application Note AN-932 2008 Martin Murnane, Chris Augusta Powering up a circuit on a printed circuit board is too often taken for granted and can cause damage and both destructive and nondestructive latch-up conditions. These problems may not be ...

  6. Digital 74HC244
    Ajoy Raman EDN Utilizing the large operating voltage range of an octal CMOS buffer, this Design Idea presents a simple 8-bit two-quadrant multiplying Digital-to-Analog-Converter (DAC) built with the buffer/line-driver IC 74HC244 . Figure 1. In ...
