CDG714 is a complementary metal oxide semiconductor (CMOS), eight channel single pole single throw (SPST) switch controlled through a three 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.
CDG714 adopts a three wire serial interface and is compatible with Serial Peripheral Interface (SPI) and QSPI ™、 MICROWIRE ™ The interface standards are compatible with most digital signal processing (DSP) interface standards. By using the output of the shift register OUT, several such devices can be connected in a daisy chain form.
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. CDG714 can also be powered by ± 2.5 V dual power supply.
