Selection Guide

Choose the MUX80X-Q1 when you need a high-voltage (up to 100V) analog multiplexer with flat RON and automotive qualification. It is ideal for automotive battery management, industrial process control, and test equipment. If your application operates below 36V and cost is critical, consider the MUX708-Q1, which is pin-compatible but has a lower voltage rating. For lower ON-resistance and non-automotive applications, the ADG5208 or MAX14778 may be alternatives, but they lack the 100V rating and automotive grade. The MUX80X-Q1 offers the best combination of high voltage, flat RON, and automotive reliability for demanding applications.

Key Differentiators

  • 100V supply voltage rating (vs MUX708-Q1)
  • Flat RON across input range (vs ADG5208)
  • Automotive qualification (AEC-Q100) (vs MAX14778)

Design Notes

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.
