Working Principle

The DG9414DQ-T1-E3 operates by using an ENABLE signal to turn a corresponding switch ON or OFF. Each switch has three pins; ENABLE (for switching ON or OFF the switch), IN for input, and OUT for output. The ENABLE signal works like a flip-flop; when it is LOW, the switch is OFF, and when it is HIGH, the switch is ON. The switch is designed to be “normally open”. When it is ON, the signals are passed through and when OFF, they are blocked.

The ENABLE signal is applied to all switches in the device, allowing them to be controlled simultaneously. The switches are designed to have a low Charge Injection, which means the signal is passed through the switch with minimal degradation. This is important for applications where signal integrity is essential.

Conclusion

The DG9414DQ-T1-E3 from Toshiba Semiconductor and Storage is a compact and low power analog switch device ideal for a variety of applications. With its low ON-resistance and charge injection, it provides signal integrity in multiplexers, demultiplexers, and other signal-handling systems. It is a versatile and reliable device that is easy to use and compatible with a variety of systems.
