Key Features
- Dual Single-Pole Quad-Throw (SP4T) Analog Switches: Each switch features four independent inputs/outputs (nY0, nY1, nY2, and nY3) and a common input/output (nZ).
- Digital Enable and Select Inputs: A digital enable input (E) and two digital select inputs (S0 & S1) are common to both switches. When E is HIGH, the switches are turned off.
- Injection-Current Effect Control: Allows signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel, eliminating the need for external diode/resistor networks.
- Clamp Diodes: Inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.
- AEC-Q100 Grade 1 Qualified: Suitable for use in automotive applications, qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1).
- Wide Supply Voltage Range: Operates from 2.0 V to 6.0 V, making it versatile for various applications.
Applications
- Automotive Systems: Qualified to AEC-Q100 Grade 1, making it suitable for use in automotive applications such as infotainment systems, driver assistance systems, and more.
