• High-performance, low-cost solution to switch
between video sources
• Wide bandwidth: 550 MHz
• Low On-Resistance: 5Ω
• Low crosstalk at 10 MHz: –90dB
• Ultra-low quiescent power (0.1µA typical)
• Single supply operation: +5.0V
• Fast switching: 10ns
• Packaging (Pb-free & Green available):
– 24-pin 150-mil wide plastic QSOP (Q)
Pericom Semiconductor’s PI5V512 is a true bidirectional 5-Port 2:1
multiplexer/demultiplexer with Hi-Z outputs that is recommended
for both RGB and composite video switching applications. With the
additional 2 ports, vertical and horizontal synchronous signals can
be switched in addition to switching the RGB and composite signals
between different components, such as DVD, VCR, PCs and etc.
The video switch can be driven from a current output RAMDAC
or voltage output composite video source.
Low On-Resistance, Low Crosstalk, Low OFF Isolation and wide
bandwidth features make it ideal for video and other applications.
The device also has exceptional high current capability which is
far greater than most analog switches offered today. A single 5V
supply is all that is required for operation. The switch is bidirectional and offers little or no attenuation of the high-speed signals at
the outputs. The PI5V512 offers a high-performance (550 MHz),
low-cost solution to switch between video sources.

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 = 5.0V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between I0, I1, and D I/O pins at indicated current through the switch. On-Resistance is determined by the
lower of the voltages on the I0, I1, and D I/O pins.

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V, control inputs only); I0, I1, and Y pins do not contribute to Icc.
4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The
I0, I1, and Y I/O pins generate no significant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design.
