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.

Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Stresses greater than those listed under
MAXIMUM RATINGS may cause permanent
damage to the device. This is a stress rating
only and functional operation of the device at
these or any other conditions above those
indicated in the operational sections of this
specification
is not implied. Exposure to
absolute maximum rating conditions for
extended periods may affect reliability.

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.
