STG3684QTR

Overview

The STG3684QTR is a low-voltage dual analog SPDT switch manufactured by STMicroelectronics. It operates within a supply voltage range of 1.65 V to 4.3 V and supports single-supply configurations. The device features two channels with a maximum on-resistance of 500 mOhms. Switching performance includes a maximum turn-on time of 55 ns and a maximum turn-off time of 30 ns. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a QFN-10 package and draws a maximum supply current of 50 nA.

Feature Summary

Dual channel SPDT configuration for signal routing
Low power dissipation suitable for portable applications
Compatible with standard digital control thresholds

Applications

Portable electronic devices requiring low voltage switching
Signal multiplexing or demultiplexing circuits
Battery-powered systems with strict power constraints

Procurement Notes

Verify the specific suffix 'QTR' against official STMicroelectronics documentation to confirm automotive qualification status, as datasheets may vary by region. Confirm RoHS compliance details directly with the manufacturer. Check for obsolescence notices or lifecycle changes before finalizing design-in decisions.

Selection Notes

Select this component when dual independent SPDT switching is required at low voltages. Ensure the application voltage does not exceed 4.3 V. Verify that the 500 mOhm on-resistance meets signal integrity requirements. Compare against the STG3682 series if lower resistance is needed.

Part Context

This part belongs to the STG3684A series of low-voltage analog switches. It shares functional similarities with other members like the STG3682 but differs in on-resistance specifications. The QFN-10 package allows for compact PCB layouts in space-constrained designs.

Replacement Considerations

The STG3682QTR is a related dual SPDT switch with lower on-resistance (approx. 4.6 Ohms) but requires verification of pin compatibility. No direct public substitute part numbers are confirmed for this specific model.
