Vinput

†

Voltage Applied to Any input pin (except D+ and D-)

-0.3V Vin

Voutput

Voltage Applied to Any output pin

-0.3V

Vin + 0.3V

For USB version, Voltages on D+ and D- signal must conform to USB Specification

Voutput must be less than 5.5V for all pins

†

If the Vinput signal is greater than VIN, current will flow from the input to the VIN pin through the
pull up resistors on the engine. In Suspend Mode, this may cause current to flow into the USB power.
This is not recommended.

PWRDWN, nGoodRead, and nBeeper are open drain outputs w/ 100K pull-ups to VIN. Actual VOH will be determined

by the parallel resistance of the 100K pull up and any external impedance.
