what will be the output voltage of each pin if the IC is powered by 3.3V.?
In datasheet, it is recommended that it will give Vcc output. Has anyone checked it.

Hi Inam,

Since V_OH is not provided for V_CC = 3.3V we must use the existing data to find V_OH .

V_OH is 2.3 V at a current I_OH of 24mA. The supply is at 3.0V so this indicates a voltage drop across the PFET of 0.7V ( V_CC- V_OH= 0.7V). Therefore with a supply at 3.3V and 24mA output current, V_OH= 3.3V - 0.7V = 2.6V.

Please refer to this FAQ What is the output voltage when the supply is Y? for further details.

Regards,

Sebastian
