Hello
Can anyone please tell me maximum power requirements of RS422 receiver AM26LV32I.
In its datasheet it is written as
-Ultra-Low Power Dissipation . . . 27 mW Typ
-235 mW With Four Receivers at 32 MHz
I am a bit confused about these statements.
Thanks
Regards

Azeem,
For maximum power needed, start with data sheet table for ICC static.
17mA is maximum. Multiplied by 3.3V (VCC) gives 56mW
Capacitance use power when switching.
There is even a formula (that also adds ICC)
Cpd is per channel that is toggling. f = bit rate / 2 (worst case)
