MAX232: max232

Part Number: MAX232

Hi!

Any one has used max232 with 2.5v supply?Is this IC behave same on supplies other than 5v?

In my project the tx and rx levels  are +/-2.5v and I have to transfer these to my pc serial port

kindly seggest how I can translate my levela to Rs232 levels

regards

  • Hello S Siddiqui,

    Unfortunately, this device requires a minimum VCC level of 4.5 V. The device may not function properly if operated below this minimum recommendation. The voltage levels you mentioned (+/- 2.5 V) seem low - are these needed for the RS-232 port (TOUT/RIN) of a PC or are these what you need on the TIN/ROUT interfaces (i.e., going to an MCU, etc.)?
