CDG715 is a complementary metal oxide semiconductor (CMOS), eight channel single pole single throw (SPST) switch controlled through a dual wire serial interface. The conduction resistance matching between switches is strict, and the conduction resistance curve is flat throughout the entire signal range. The conductivity of each switch is the same in both directions, and the input signal range can be extended to the power supply voltage range. The data is written to these devices in 8-bit format, with each bit corresponding to a channel.

CDG715 adopts a dual wire serial interface compatible with the I2C interface standard. CDG715 has four hard wired addresses, which are selectable through two external address pins (A0 and A1). These pins allow the user to set two LSBs for a 7-bit slave address. Up to four devices can be connected to the bus.

When powered on, all switches are in the off state, and the internal registers are all zero.

This device has low power consumption and a working voltage range of 2.7 V to 5.5 V, making it suitable for many applications. CDG715 can also be powered by ± 2.5 V dual power supply.
