Product Description

The PI3V312 is a 4-port, 2:1 Multiplexer/ Demultiplexer with 3-state outputs. The switch introduces no additional ground bounce noise or propagation delay.
Low On-Resistance and High bandwidth make it ideal for video and other applications. Also this device has exceptionally low crosstalk and off-isolation, which is far greater than most analog switches offered today. A single 3.3V supply is all that is required for operation.
The PI3V312 offers a high-performance (500MHz), low-cost solution to switch between video signals that have high bandwidth.


  • Near-Zero propagation delay
  • 5Ω switches connect inputs to outputs
  • High signal passing bandwidth (500MHz)
  • Beyond Rail-to-Rail switching
  • 5V I/O tolerant with 3.3V supply
  • 1.8V, 2.5V and 3.3V supply voltage operation
  • Hot insertion capable
  • Industrial operating temperature: -40ºC to +85ºC
  • 2KV ESD Protection (human body model)
  • Latch-up performance >250mA per JESD17
  • Packaging (Pb-free & Green):
    – 16-pin QSOP (Q)
    – 16-pin TSSOP (L)
