1-01-1993 | The Type Y112 fluoractor(TM) fromTexas Instruments is a specially designed thyristor for starting fluorescent tubes. Its main advantages...

1-12-1992 | Nowadays, with the advent of SMD (surface mountdesign), it is possible to construct tiny circuits. In the case of crystal oscillators th...

1-12-1992 | Although there are a nurnber of hybrid output modules on the market, very few of them combine compactness with reasonable price and good...

1-12-1992 | A negative supply voltage may be obtained easily with the use of a special inverter IC. Such ICs are not always readily available, howeve...

1-12-1992 | This circuit provides a simple means of implementing a 'soft-start' on heavy mains loads. Basically, this is achieved with the aid of hig...

1-12-1992 | Flash-EPROMS are becoming increasingly popular, in spite of their being harder to reprogram than EEPROMs. That difficulty is, however, co...

1-12-1992 | If you ever need to derive a 5 V line from, say, a 15-25 V supply, National Semiconductors LM1575 and LM2575 are ideal. These switched 5-...

1-12-1992 | The MAX252 from Maxim ts a special IC for designing an electrically isolated RS232 connection. Such links are particularly important when...

1-11-1992 | Today, Radio or Wireless as we used to call it, has beeome so much part of our lives that is difficult to appreciate the fact that in ear...

1-11-1992 | In the late 1960s, the International Electrotechnical Committee, IEC, set up a working group to devise symbols for binary logic. The work...
