QS32390QG - Renesas Electronics

Description: The QS32390 provides a 16:8 multiplexer logic switch. The QS32390 has an internal 25 ohm resistor to reduce reflection noise in high-speed applications. The enable inputs connect one of two inputs to the common I/O pin, respectively. The multiplexer function can be used to select and route logic signals for zero delay, isolate bus capacitance, form crossbar switches, etc. The QS32390 operates at -40C to +85C.

QS32390QG Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APN) document, which includes thermal vias, copper pours, and component placement guidelines to ensure optimal thermal performance.
  • The power-up sequence is critical for the QS32390QG. Renesas recommends powering up the VCC pin first, followed by the VDD pin, and then the input signals. A specific power-up sequence is provided in the datasheet and application notes.
  • Renesas recommends using high-frequency, low-ESR decoupling capacitors (e.g., 100nF, 1uF, and 10uF) placed close to the VCC and VDD pins to minimize noise and ensure stable operation.
  • Renesas provides a troubleshooting guide in their application notes, which includes steps to check output signal integrity, clock signal quality, and power supply noise. Additionally, using an oscilloscope and logic analyzer can help identify issues.
  • The QS32390QG is rated for operation from -40°C to +125°C (junction temperature). However, the maximum operating temperature range may vary depending on the specific application and environmental conditions.
