MAX14662ETI+ Datasheet PDF - Maxim Integrated

●The MAX14662ETI+ is a beyond the rails 8 x SPST switch in 28 pin TQFN package. It is a serially controlled switch for general purpose signal switching applications. The number of switches makes the device useful in a wide variety of applications while serial control maximizes flexibility with minimal pins. This device features beyond the rails capability so that ±5.5V signals can be passed with any single supply between 1.6V and 5.5V. The serial control is selectable between I2C and SPI. Both modes provide individual control of each independent switch so that any combination of switches can be applied. I2C mode provides two address select pins allowing for addressing up to four devices on a single bus. The SPI mode includes DOUT pin that can be used to chain multiple devices together with single select signal. The MAX14662 is used in audio switching/multiplexing and port protection.
