Description
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 = 25C 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.

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.

Minimum input voltage for logic LOW. Input current of the digital input. Propagation delay measured between 50% of the digital input to 90% of the analog output when switch is turned ON. The peak analog voltage is 0.714V. Propagation delay measured between 50% of the digital input to 90% of the analog output when switch is turned OFF. The peak analog voltage is 0.714V. Frequency response of the switch in the ON state measured at 3dB down. Unwanted signal coupled from channel to channel, measured in -dB. XTALK = 20 LOG VOUT/VIN. This is nonadjacent crosstalk. Off isolation is the resistance (measured in -dB) between the input and output with the switch off (NO).
