Hi ,
I would like to know the maximum differential O/P voltage swing of Rs422 Drivers,I had referred datasheets of TI's Differential drivers and found only the minimum and typical values mentioned, I would be glad,if their is any reason behind their absence.
Can I use the supply voltage to IC as maximum differential O/P voltage swing,I have attached snapshots of datasheets of parts I have referred.
Regards,

Harish,
VCC will indeed limit the maximum.
Most RS422 devices show the output stage schematics in the data sheets.
On the AM26C31 for example, there is no diode drop to ground but there is a NPN base emitter diode from VCC so maximum could be reduced to VCC -0.5V
