QS4A110QG

Overview

The QS4A110QG is a high-performance CMOS analog switch manufactured by Renesas Electronics Corporation, formerly IDT. It features two independent 5PST (Single Pole Single Throw) channels with bidirectional signal paths and 3-state outputs. The device operates on a single 5V supply and provides an ultra-low quiescent current of 3 µA. Key electrical parameters include a maximum on-resistance of 17 ohms, a -3dB bandwidth of 1.8 GHz, and a charge injection of 1.5 pC. Switching times are specified at a maximum of 6 ns for turn-on and 6.5 ns for turn-off. The component is housed in a 24-lead QSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

High-speed signal routing capability supported by a 1.8 GHz bandwidth
Ultra-low power consumption suitable for battery-operated systems
Bidirectional switching with TTL-compatible control inputs

Applications

High-performance video signal switching
Audio signal switching
Telecommunications routing applications

Procurement Notes

Verify the manufacturer status carefully as this component is listed as End-of-Life (EOL). Official documentation indicates an EOL notification dated January 31, 2023. Sourcing should focus on authorized distributors or surplus markets, ensuring strict adherence to RoHS3 compliance requirements. Confirm the specific suffix 'QG' corresponds to the standard 24-QSOP package configuration before procurement.

Selection Notes

Select this component when a dual-channel analog switch with high bandwidth and low on-resistance is required. The 17-ohm on-resistance and 1.8 GHz bandwidth make it suitable for demanding signal integrity applications. Ensure the design accommodates the 24-pin QSOP footprint and that the single 5V supply voltage aligns with the system power architecture.

Part Context

The QS4A110QG belongs to the QS4A110 series of high-performance CMOS switches. This series was originally developed by Integrated Device Technology (IDT) and is now managed by Renesas Electronics following corporate acquisitions. The part represents a specialized solution for analog signal routing within mixed-signal environments requiring fast switching speeds.
