Analog switches & muxes

High voltage multiplexers are capable of multiplexing signals surpassing 6V. The ability to handle high voltages allows the high voltage multiplexers to be utilized in various industrial applications where high voltage signal swings are present such as ultrasound, test and measurement, factory automation, etc.

• Devices available that support both single and dual supply
• Consistent parameters across supply voltages
• Latch-up immune architecture
• Handles signals up to 100 V

A fault event occurs when the voltage on a signal pin exceeds the supply voltage of a multiplexer. Fault events can be caused by any condition that causes a high voltage to be applied to a signal pin, such as power supply sequencing errors or miswiring. Fault protected multiplexers prevent signals and damage caused by fault events up to ±60 V for device inputs. 

• Protects downstream devices from fault events
• Contain interrupt flags to indicate fault status
• Maintains fault protection when in an off-state
• Precision features: low Ron, low Con, flat-on resistance
• Latch-up immune architecture

Typically, multiplexers support rail-to-rail operation, where only signals within the supply voltage range can be passed. However, with beyond the supply capable multiplexers, signals that exceed the supply voltage can be passed. The ability to go beyond the supply allows for a reduction in the amount of supply rails needed.

• Passes positive and negative signals that exceed supply voltage
• Protection features: powered-off protection, over-temperature protection
• Precision features: low Ron, low Ron flatness, low THD+N
• Up to 1A current support
• Use cases include: audio, industrial applications, relay replacement, etc.

I3C is an improvement upon previous communication protocols I2C and SPI. I3C compatible multiplexers are optimized for the improved specifications of the I3C protocol. 

• Increase the number of peripherals a controller can communicate with
• Maintains a low bus line capacitance below 50pF
• Supports open-drain and push-pull interfaces
• High bandwidth to maintain integrity of 12.5MHz signals
• I3C voltage level support: 1.2V, 1.8V, 3.3V

Leakage current refers to the small amount of current that flows through a device when in either an on or off state. Excessive leakage current increases both the power consumption and noise of a system. Our ultra-low leakage multiplexers minimize the amount of leakage current reducing the noise and power of the system.

• High precision features: low Con, low Ron, low charge injection
• Optimized for low power, high accuracy operations
• Wide supply ranges: up to ±50 V
• Low supply current
