3.3V High Speed 2 : 4 Differential Mux/Demux
Features
Description
ꢀÎ2:4 Differential Multiplexer/Demultiplexer
ꢀÎBidirectional Operation
ꢀÎCan be used in
e PI3DBS3224 is a 2:4 bidirectional multiplexer for high-
speed differential and single ended signal applications (up to
720 Mbps). e PI3DBS3224 can be used in a 1:4 or dual 1:2
multiplexer/demultiplexer configuration. e PI3DBS3224 of-
fers a high BW of 1.2 GHz with channel RON of 13 Ω (Typ).
à
à
à
Single 1:4 Configuration
Dual 1:2 Configuration
Fan out 1:2 Configuration
e PI3DBS3224 can also be used to fan out a differential or
single ended signal pair to two ports simultaneously (fan-out
configuration). e BW performance is lower in this configura-
tion.
ꢀÎHigh BW (1.2 GHz Typ)
ꢀÎLow RON and CON:

à
13 Ω RON Typ
9 pF CON Typ
ꢀÎESD Performance (I/O Pins)
e PI3DBS3224 operates with a 3 to 3.6V power supply. It
features ESD protection of up to 8-kV contact discharge and
2-kV Human Body Model on its I/O pins.
à
à
8-kV Contact Discharge (IEC61000-4-2)
2-kV Human Body Model per JESD22-A114E (to
GND)
ꢀÎESD Performance (All Pins)
e PI3DBS3224 provides fail-safe protection by isolating the
I/O pins with high impedance when the power supply (VCC) is
not present.
