STG3693QTR

Overview

The STG3693QTR is a high-speed CMOS low voltage quad analog SPDT switch or 2:1 multiplexer/demultiplexer fabricated in silicon gate C2MOS technology. It operates from a single supply of 1.65 V to 5 V, making it suitable for portable applications. The device features ultra-low power dissipation with an ICC of 0.3 µA at TA = 125 °C and low on-resistance of 4 Ω at VCC = 3.0 V and TA = 25 °C. It provides a typical bandwidth of 800 MHz on all channels and includes protection circuits against static discharge, exceeding JESD22 2000-V human body model ESD performance. Latch-up performance exceeds 100 mA per JESD 78, Class II.

Feature Summary

Ultra-low power dissipation and low on-resistance for efficient signal routing
Wide operating voltage range supporting 1.65 V to 5 V single supply operation
High bandwidth capability up to 800 MHz for high-speed data switching
Robust ESD immunity and latch-up protection for reliable operation

Applications

Portable electronic devices requiring low voltage operation
USB 2.0 high-speed (480 Mbps) signal switching compliant systems
Multiplexer and demultiplexer configurations in communication equipment

Procurement Notes

Verify the component authenticity by checking the marking code and package details against the official datasheet specifications. Ensure the QFN16L package dimensions match the required footprint. Confirm the ordering suffix corresponds to the tape and reel packing type specified in the product summary. Cross-reference the part number with authorized distributors to ensure compliance with RoHS standards.

Selection Notes

Select this component when a quad SPDT switch with wide voltage tolerance is required. Consider the 5 V tolerant control inputs if interfacing with higher voltage logic levels while maintaining low voltage core operation. Evaluate the thermal requirements as the exposed pad must be soldered to a floating plane for proper heat dissipation and electrical isolation.

Part Context

The STG3693 belongs to STMicroelectronics' family of low voltage analog switches. It shares similar functionality with other models in the series but offers specific voltage ranges and performance characteristics tailored for portable and high-bandwidth applications. The QFN16L package provides a compact solution for space-constrained designs.
