DESCRIPTION
The SGM4522Q is a single 8-channel CMOS analog multiplexer with injection current control. The device has three control inputs that can be used as selecting one of the 8 channels (Sx) to connect to the common terminal (Dx). The multiplexer supports bidirectional signal transmission in the voltage range from GND to VDD.
All logic inputs of the SGM4522Q are allowed to be equal to the power supply voltage and compatible with TTL and CMOS logic thresholds standards during normal operation of the power supply. Besides, all control inputs are also designed with fail-safe function. It allows the voltage of all control pins within the maximum absolute withstand voltage range to exceed the VDD without damaging the device.
The injection current control function of the SGM4522Q allows signals on disabled signal channels to exceed the VDD without affecting the enabled signal channel. In addition, all pins of the SGM4522Q except GND are not designed with internal diodes path to the VDD pin, so as not to damage the components connected to the power pin and avoid injecting reverse current into the power supply.
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM4522Q is available in Green TSSOP-16 and TQFN-2.5×3.5-16AL packages. It operates over an operating temperature range of -40℃ to +125℃.
