DG417BDY is a monolithic CMOS integrated circuit that incorporates low current analog switches, multiplexers, demultiplexers with SPST and SPDT switch elements. Standardized parameters such as maximum on-state resistance and off-state leakage current along with supply voltage range, make this device ideal for interface designs. It is useful in implementing circuit switching and analog multiplexing applications.

The device features two 74HC/HCTT, an 8-channel SPST analog switch (with a nominal R_ON of 45 ohms) and two 8-channel multiplexers/demultiplexers (with R_CH of 10 ohms and Off-State leakage current of 10 nA). The output pins provide both logic and analog outputs. The switches and multiplexers/demultiplexers are controlled by a logic input that includes logic threshold and hysteresis. The logic input voltage range is from 0V to VDD-2V, making the device suitable for operation with a single power supply.

The DG417BDY\'s construction is based on N-channel MOSFET technology for low power application. It is a pin-for-pin replacement for the DG417DY but with improved switching characteristics. The DG417BDY delivers an improved R_ON (vs. DG417DY) of 45 ohms at room temperature and a lower Off-State current of 10nA (vs. 30nA).

The amazing features of the DG417BDY make it an ideal choice for many applications such as transformerless microphone preamps, sample-and-hold circuits, video switching and digital data transmission. The device provides isolation between the analog and digital circuits and provides an economical way to reduce noise and distortion. It also provides a useful solution for fighting leakage current and power consumption.

In summary, the DG417BDY device is an effective integrated low-power analog switch/multiplexer/demultiplexer solution which can be used in a wide variety of interface designs. The device provides high on-state resistance, low off-state current, and switching characteristics. This makes it ideal for design implementations in many different applications.
