The PO3VT3245A is a Hot Insertion 8-Bit, 2-Port,
Low Voltage Translator Bus Switch.
PO3VT3245 can do voltage level shifting from
3.3V to 2.2V or 2.5V to 1.6V.
The switch introduces no additional ground
bounce noise or propagation delay.

For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
Typical values are at Vcc = 3.3V, 25°C ambient.
This parameter is guaranteed but not tested.
Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
