PRODUCTION DATA
The inputs and outputs for this device enter a high-impedance state when either supply is <100 mV, requiring one supply to connect to the device. Note: the bus-hold circuitry always remains active even when the device is disabled and all outputs are in the high-impedance state.
Either supply can be disconnected (floated), while the other supply is still connected and the device will maitain the maximum supply current specified by ICCx(floating), in the Electrical Characteristics. The I/O's will not enter a high-impedance state unless the supply is disconnected after it is driven to <100 mV. Ioff(float) in the Electrical Characteristics specifies the maximum leakage into or out of any input or output pin on the device.
