Technical Note
●Notes for use
1. Numbers and data in entries are representative design values and are not guaranteed values of the items.
2. Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to
verify circuit characteristics for your particular application. Modification of constants for other externally connected
circuits may cause variations in both static and transient characteristics for external components as well as this Rohm IC.
Allow for sufficient margins when determining circuit constants.
3. Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr),
may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode)
when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at
times where the absolute maximum ratings may be exceeded.
4. GND potential
Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND
at any time, regardless of whether it is a transient signal or not.
5. Thermal design
Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in
actual states of use.
6. Short circuit between terminals and erroneous mounting
Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other
components on the circuits, can damage the IC.
7. Operation in strong electromagnetic field
Using the ICs in a strong electromagnetic field can cause operation malfunction.
8. For clamp operation stability
Set the output impedance of the stage before input pin no more than 1 kΩ.
9. An input clamp capacitor will cause delay in operation at power on. Therefore, it is recommended to use a clamp
capacitor no larger than 0.1 µF (0.01µF (FZ) ceramic capacitor is recommended).
10. TheBA7653AF, BA7653AFV and BA7652AF are 3-input, 1-output switch. If it is used as a 2-input, 1-output switch, by
leaving one input Open and unused, the Open input pin will oscillate. However, this does not affect other pins and is
not particularly a problem for operation. If necessary, connect the input pin to GND via a capacitor or connect the input
pin directly to VCC to stop oscillation.
11. CTL pin is in indeterminate status when left Open. Set it at “H” or “L” level.
12. For superimposed, a 1.7v DC voltage should be applied directly to an input pin.
