DG309BDY-T1 analog switch multiplexer is a single-pole double-throw (SPDT) switch. It is designed for applications requiring low power, high speed, and high fidelity signal routing in industrial, automotive, and consumer applications. The DG309BDY-T1 is a monolithic, silicon device with a dielectrically isolated dual-input differential pair. The device can be used as an 8-bit mux or 16-bit demux and due to its low on-resistance and high drive capability, it can be used as a current- or voltage-controlled switch.

DG309BDY-T1 is designed to operate over the extended industrial temperature range of -40°C to 85°C and requires a single supply of 5V. It can be powered down to reduce power consumption when not in use. The low power consumption and wide supply voltage range make the device ideal for portable applications.

The device enables multiple analog signals to be routed to one output. The DG309BDY-T1 provides 8-way multiplexing capability and 16-way demultiplexing capability and can handle extremely high switching speeds of up to 4 Gb/s between multiple channels. The low input capacitance of the device helps to reduce crosstalk between channels. In addition, the device has a low off-state leakage current of 1 nA, making it suitable for high frequency digital and analog signal routing.

The DG309BDY-T1 can be powered via the Enable Control or the Clock Input. Both the Enable and Clock Inputs are TTL/CMOS compatible and are engaged via logic “0” or logic “1”. The Clock Input is used to determine the number of inputs and the Enable Input can be used to enable or disable switching functions. The logic control signals can be used to enable and disable functions such as channel selection, reset and power saving states.

When using the device as a multiplexer, the Enable Control and Clock Input are used to select the input channel. The device supports 8-way Multiplexing and the logical output will determine the active channel. When used as a demultiplexer, the Enable Control and Clock Input are used to select the output channel. The device supports 16-way Demultiplexing and the logical output will determine the active channel.

The device has very low on-resistance of 25Ω maximum and a very low off-state leakage current of 1 nA. This low on-resistance and off-state leakage current make the device suitable for high frequency digital and analog signal routing applications. The device also has high drive capability and is designed to handle up to 4 Gb/s of data.

In conclusion, the DG309BDY-T1 device is an ideal choice for applications requiring low power, high speed and high fidelity signal routing. It provides low on-resistance and off-state leakage currents, high drive capability, and fast switching speeds. Its wide supply voltage range and temperature range make it ideal for use in industrial, automotive, and consumer applications.
