INA is selected by applying a high-level voltage to the CTL pin, and INB is selected by applying a low-level voltage. When the power save pin (pin 8) is set to high level, the current to the SW block's output transistors is reduced to lower the circuit current. Even during low power mode, signal switching can be performed normally as long as there is no drop in frequency characteristics. 2) CMOS analog SW block 2 SDA and SDC signals are switched via an I C bus to handle two channels of HD and VD synchronization signals, and to exchange information bidirectionally between a computer and a monitor. 2 The switching circuits used by this IC handle are configured as CMOS analog switches in order to handle I C BUS signals and to transmit input and output signals bidirectionally.

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. [BA7657S/F] 8) External resistance for analog SW block The frequency characteristics of analog switches vary according to the output load capacity. Set an external resistance value of R0 to keep frequency characteristics as flat as possible. 9) Polarity of input coupling capacitor When this IC is switched, variation is approximately 3.7 V when the input pin's DC voltage has been selected, but is 0 V when the input pin's DC voltage has not been selected. Therefore, the input coupling capacitor's polarity should be set so as to avoid applying a reverse voltage to capacitors, whether the input pin's DC voltage has been selected or not. 10) High-frequency characteristics of input coupling capacitor Since this IC handles signals at very high frequencies, when using an electrolytic capacitor as a coupling capacitor for input, be sure to insert high-frequency oriented ceramic capacitors (approximately 0.01 µF) in parallel. 11) Layout of target board Since this IC handles signals at very high frequencies, be sure to insert the power supply pin's decoupling capacitor close to the IC's power supply pin. Also, use as large a GND pattern as possible. 12) Switching speed Since this IC changes the DC voltage of input pins when switching, some time is required for switching. The amount of switching time can be determined by time constants that are in turn determined by the capacity of the coupling capacitor connected to the input pin, and the IC's internal input resistance. When using the recommended input coupling capacitor whose capacitance is 47 µF, the switching time is approximately 0.5 seconds. 14/16 ●Cautions on use (2/2) [BH7659FS] 13) External resistance for analog SW block The frequency characteristics of analog switches vary according to the output load capacity. Set an external resistance value of R0 to keep frequency characteristics as flat as possible. 14) Polarity of input coupling capacitor When this IC is switched, variation is approximately 3.5 V when the input pin's DC voltage has been selected, but is 0 V when the input pin's DC voltage has not been selected. Therefore, the input coupling capacitor's polarity should be set so as to avoid applying a reverse voltage to capacitors, whether the input pin's DC voltage has been selected or not. 15) High frequency characteristics of input coupling capacitor Since this IC handles signals at very high frequencies, when using an electrolytic capacitor as a coupling capacitor for input, be sure to insert high-frequency oriented ceramic capacitors (approximately 0.01 µF) in parallel. 16) Layout of target board Since this IC handles signals at very high frequencies, be sure to insert the power supply pin's decoupling capacitor close to the IC's power supply pin. Also, use as large a GND pattern as possible. ●Selection of order type B A 7 6 5 7 S E 2 Part.
