FEATURES:

DESCRIPTION:

• Patented technology
• High signal -3db passing bandwidth at 3.5Gbps
  or 1.75GHz
• 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 12pin DFN package

Potato Semiconductor’s PO3B10A is
designed for world top performance using
submicron CMOS technology to achieve GHz
high bandwidth.

The PO3B10A is a 2-channel, 2:1 Multiplexer /
Demultiplexer with  3-state outputs. The switch 
introduces no additional ground bounce  noise or 
propagation delay.
