PO3B3257A
Quad 2:1 Mux/DeMux
10/15/07
High Bandwidth Potato Chip
FEATURES:
DESCRIPTION:
• Patented technology
• High signal -3db passing bandwidth at 1.2GHz
• Near-Zero propagation delay
• VCC = 1.65V to 3.6V
• Ultra-Low Quiescent Power: 0.1µA typical
• Ideally suited for low power applications
• Industrial operating temperature: -40°C to +85°C
• Available in 16pin 173mil wide TSSOP package
Potato Semiconductor’s PO3B3257A is
designed for world top performance using
submicron CMOS technology to achieve GHz
high bandwidth.
Pin Configuration
The PO3B3257A 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.
