ON
The PI3DBV40 is a 8- to 4-channel multiplexer/demultiplexer.
Industry leading advantages include a propagation delay of less
than 250ps, resulting from its low channel resistance and I/O
capacitance. The device multiplexes differential outputs from a
video source to one of two corresponding outputs or switches two
inputs to a common display. The switch is bidirectional and offers
little or no attenuation of the high-speed signals at the outputs. It
is designed for low bit-to-bit skew, high channel-to-channel noise
isolation and is compatible with various standards, such as LVDS
and TMDS.
• Channel On-Capacitance: 9.5pF (typical)
• V Operating Range: +3.0V to +3.6V
CC
• ESD>2000V . . . Human Body Model
• >500 MHz bandwidth (or data frequency)
• Packaging (Pb-free & Green available):
48-pin, 240-mil wide plastic TSSOP (A)

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between A and B pins at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (A & B) pins.
4. This parameter is determined by device characterization but is not production tested.
5. Measured on worst case corner pin.

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Guaranteed by design.
3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The
time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of
typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is
determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.

Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, the output
enables or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is advised for all CMOS devices. It is recommended to always apply V before applying signals to
CC
the input/output or control pins.
