Potato Semiconductor’s PO3B1000A is
designed for world top performance using
submicron CMOS technology to achieve GHz
high bandwidth.
The PO3B1000A is a 10-Bit, 2-Port Bus Switch.
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.
