DESCRIPTION:
Potato Semiconductor’s PO3B20A is
designed for world top performance using
submicron CMOS technology to achieve GHz
high bandwidth.
The PO3B20A is a 4-channel, 2:1 Multiplexer /
Demultiplexer with 3-state outputs. 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.
