Analog switches & muxes

High-voltage multiplexers are capable of multiplexing signals surpassing 6V. The ability to handle high voltages allows the 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 100V

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 ±60V 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 R_on, low C_on, 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 R_on, low R_on 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 C_on, low R_on, low charge injection
• Optimized for low-power, high-accuracy operations
• Wide supply ranges: up to ±50V
• Low supply current
