●Description

These video switching ICs, which contain two or three 2-input circuits, were developed for switching TV, DVD, and other

video signals. Input pin formats can be selected from bias mode (R=20 kΩ), sync-tip mode, and pedestal clamp mode.

Having a large dynamic range and broad frequency characteristics, these switches are suited to a wide range of applications

from audio signals to video signals.

●Features

1) Contain three 2-input, 1-output switch circuits

2) Power supply voltage (4.5~5.5 V)

3) Low power consumption

4) Good frequency characteristics

5) Large dynamic range

6) Bias input (BA7602F)

Sync-tip clamp input (BA7603F)

Pedestal clamp input (BA7606F, BA7606FS)

Bias input + sync-tip clamp input (BA7607F, BA7609F, BA7627FV)

●Notes for use

1) Numbers and data in entries are representative design values and are not guaranteed values of the items.

2) Although we are confident in recommending the sample application circuits, carefully check their characteristics further

when using them. When modifying externally attached component constants before use, determine them so that they

have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only

for static characteristics but also including transient characteristics.

3) Absolute maximum ratings

If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may be

damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you think of a case in

which absolute maximum ratings are exceeded, enforce fuses or other physical safety measures and investigate how

not to apply the conditions under which absolute maximum ratings are exceeded to the LSI.

4) GND potential

Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the

voltage of each pin does not become a lower voltage than the GND pin, including transient phenomena.

5) Thermal design

Perform thermal design in which there are adequate margins by taking into account the allowable power dissipation in

actual states of use.

6) Shorts between pins and misinstallation

When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is

misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by a foreign

substance coming between pins of the LSI or between a pin and a power supply or a pin and a GND.

7) Operation in strong magnetic fields

Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction.

8) A bias input coupling capacitor on the order of 10 µF~33 µF is appropriate.

9) A clamp input coupling capacitor on the order of 0.1 µF~1 µF is appropriate.

10) Make the clamp pulse width of the BA7606F/FS at least 1 µs.
