<p style="margin-bottom:12.0pt">Ceka me redesign zarizeni komunikujiciho po RS-485.
<br>
V puvodnim zarizeni byl 5V MCU a 5V driver s plnou kapacitou (max 32 zarizeni na lince).<br>
Nyni bude MCU 3.3V a rad bych drives s nizsi kapacitou.<br>
Muzete doporucit nejaky bezne dostupny 3.3V RS-485 driver s 1/2 az 1/8 kapacitou, nizkou spotrebou a rozunou cenou ?<br>
Pekne drivery nabizi Maxim, ale cena za ktere je prodava farnell je trochu mimo.<br>
<br>
Pro jisottu, neni problem s interoperabilitou 3.3V drivru na lince s 5V drivery?<br>
<br>
Dekuji<br>
