Hi,

I have TTL logic output level +5v and 0v
I want to convert it to +5v and -5v. How to ?

KSA
 

Putting a MAX232 you will convert TTL levels (0-5v) to RS232 levels (-12/12V), so just a resistor divider will attenuate the voltages to your needs..
 

Hi,
Search for ICL7660 IC
It makes this conversion.
Best regards
 

You can use this circuit.
Dont forget this is also inverter.
 

I think the solution depends on the speed you require.
regards
 

And why not use an MC1488 (rs232 driver) with +5V and -5V power supply ?
