CCA
Once the device is enabled (OE = low), even if the input is floating, output may be either
on high or low logic level only, not in a high-impedance state. Output is in a high-
impedance state only when OE = high.
Unused I/O channel should be connected to GND or to the corresponding supply.
The OE and DIRn block is powered by V

Any input high level can be higher than the corresponding input supply voltage, up to

If V
An or Bn.
If the ST2G3236QTR is used in a UART application, there is a possibility of floating
input condition if the cable is disconnected, therefore a pull-down resistor is
recommended on the input port.
Apply power to either V
Apply power to the OE input and to the respective data inputs. This may occur at the
same time as step 1.
Apply power to the other V
Drive the OE input LOW to enable the device.
Drive the OE input HIGH to disable the device.
