Time-tag impulses with zero-crossing circuit -  24-Jan-02 Issue of EDN  A "constant-fraction discriminator" usually performs the time-tagging of impulsive events, which have a peaking time of the signal amplitude. The implementation of this technique requires a delay in the input signal of approximately the same amount as the signal's rise time. You can attain this delay by using a coaxial cable of an appropriate length..... [Design Idea by Elio Rossi, Itesre-CNR, Bologna, Italy]

Trigger a TTL circuit from ECL levels -  8-Nov-01 Issue of EDN  ECL circuits typically have relatively small logic spans of approximately 800 mV. Because of the small span, to drive TTL circuits from ECL levels normally entails the use of level converters, such as the MC10125, or comparators. Such circuits are relatively power-hungry and expensive. However, they are sometimes simply unnecessary..... [Design Idea by Lukasz Sliwczynski, University of Mining and Metallurgy, Krakow, Poland]

Two Transistors Form Bidirectional Level Translator -  11/07/96 EDN-Design IdeasThis example illustrates a translation from 5 to 3V, but it can accommodate almost any other voltage levels, provided the logic-low levels are equal (usually0V]. Translations from 1 to 100V are possible, albeit rather slow. The key to this circuit is the unusual cross-coupling of the emitters.....

Two Wire LCD Interface using PIC16cf84 -  (schematic / Circuit design added 9/02)
Two-Transistors Form Bidirectional Level Translator -  You often need to convert a logic signal from one power supply voltage to another.  This conversion is a relatively simple task, unless the signal happens to be bi-directional. Serial buses such as Access.bus, I2C, and SBI use bi-directional data lines. Some buses may require translating logic from one voltage to another; for example.....[Jim Hagerman, Nokia Mobile Phones, San Diego, CA] [Jim Haggerman, Hagerman Technology LLC]
