MUX80X-Q1 Descripción general
An analog multiplexer is a semiconductor device that routes one of several analog input signals to a single output, controlled by digital select lines. In the hierarchy of signal routing components, an analog multiplexer falls under analog switches and multiplexers, which are part of the broader category of interface ICs. These devices are essential in data acquisition systems, test equipment, and automotive electronics where multiple sensor signals need to be selectively measured or routed.
Key features of the MUX80X-Q1 include latch-up immunity, 1.8V logic compatibility, and flat ON-resistance (RON) across the input voltage range. The flat RON minimizes signal distortion and ensures accurate signal transmission. The devices support bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins, making them versatile for both analog and digital multiplexing. The 1.8V logic compatibility allows direct interface with modern low-voltage microcontrollers and FPGAs without additional level shifting.
Technically, the MUX80X-Q1 devices are built on a high-voltage CMOS process that enables operation up to 100V. The flat RON characteristic is achieved through careful design of the switch architecture, providing a nearly constant resistance over the full input voltage range. This reduces harmonic distortion and improves signal integrity, particularly in precision measurement applications. The latch-up immunity ensures robust operation in harsh automotive environments where transient voltages are common.
Typical applications include automotive battery management systems, industrial process control, and automated test equipment. In automotive battery management, the MUX80X-Q1 can route voltage and temperature sensor signals from multiple battery cells to a single ADC, reducing component count and cost. In industrial process control, it enables multiplexing of analog sensor signals from various points in a plant to a central monitoring system. The high voltage rating and automotive qualification (Q1) make it suitable for 48V automotive systems and other high-voltage applications.
When designing with the MUX80X-Q1, ensure that the supply voltage does not exceed the absolute maximum rating of 100V. Proper decoupling of the supply pins with 0.1uF ceramic capacitors is recommended to maintain stable operation. Additionally, consider the ON-resistance and its effect on signal attenuation, especially in high-impedance circuits.

Notas de diseño
Ensure the supply voltage (VDD to VSS) does not exceed the absolute maximum rating of 100V. Use 0.1uF ceramic capacitors close to the VDD and VSS pins for decoupling. For dual supplies, maintain symmetric voltages to avoid exceeding the common-mode input range.
Place the MUX80X-Q1 close to the signal sources to minimize trace length and reduce parasitic capacitance. Use a solid ground plane under the device to reduce noise. For high-voltage signals, maintain adequate spacing between traces to prevent arcing.
Do not apply signals to the Sx or Dx pins when the supply is off, as this can cause latch-up. Ensure the logic control signals (A0-A2, EN) are within the specified logic levels (1.8V compatible). Avoid exceeding the maximum input voltage on any pin relative to VDD or VSS.
