Hello
I was reading a schematic and I found this chip: 74HC541PW. What is this?
(I am supposing this is the same as 74HC541)
I found the datasheet:
**broken link removed**
It says it is a "octal non-inverting buffer/line driver with 3-state outputs".... what???
Can someone explain this in simpler words?
Reading the schematic, it seems it is something to change level voltage?? You see, the schematic is this one:
**broken link removed**
and there, by putting say 3.3V to 74HC541 Vcc, the 5V signals (from an arduino ) can be changed to 3.3V signals for a LCD
and vicecersa, by putting 5V to Vcc the 3.3V signals of the LCD can be converted to the required 5V signals (of the arduino)
Is this correct???
thanks a lot
