MAX3232E: Operation at VCC ~= 4.4V?

Antenna_Head
Genius 11395 points
Part Number: MAX3232E

MAX3232E has recommended VCC specs of 3.3V +/- 0.3V or 5.0V +/-0.5V.  First page of data sheet indicates, "Operates with 3V to 5.5V VCC Supply".  

Any issue operating this part at VCC = 4.4V?  (This is a diode drop below 5V).  It seems like it would be just fine, but the recommended specs are oddly specific to the ranges listed.

Thanks, Best, Steve

    Hi Steve,

    You can totally operate the device at 4.4V. The values you see in 6.3 for the supply voltage is what TI tested the device with. They inputted 3V+-0.3V and 5V+- 0.5V. So this should give you a rough idea on what your system will operate at based on your desired input voltage.

    Best,
