QS3253S1G8 - Renesas Electronics

Description: The QS3253 is a high-speed CMOS TTL-compatible dual 4:1 multiplexer/ demultiplexer with 3-state outputs. The QS3253 is function and pinout compatible version of the 74F253, 74FCT253, and the 74ALS/AS/ LS253 dual 4:1 multiplexers. The low ON resistance of the QS3253 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3253 operates at -40C to +85C.

QS3253S1G8 Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APN) documents, which includes thermal vias, thermal pads, and heat sink recommendations to ensure optimal thermal performance.
  • The QS3253S1G8 has an internal overcurrent protection (OCP) feature, but it's recommended to add an external OCP circuit to ensure reliable operation. Renesas provides guidelines for implementing OCP in their application notes and design guides.
  • The recommended input capacitor value and type depend on the specific application and operating conditions. Renesas recommends using a low-ESR ceramic capacitor with a value between 4.7uF to 10uF, but the optimal value should be determined through simulation and testing.
  • Renesas provides EMC guidelines and recommendations in their application notes and design guides, including layout considerations, filtering, and shielding techniques to ensure EMC compliance.
  • The QS3253S1G8 has an operating temperature range of -40°C to +125°C, but the maximum operating temperature range may vary depending on the specific application and operating conditions. It's recommended to consult with Renesas or a qualified engineer to determine the maximum operating temperature range for a specific design.
