STG5223QTR

Overview

The STG5223QTR is a low voltage dual SPDT analog switch fabricated in silicon gate C2MOS technology. It operates from a single supply of 1.65 V to 4.3 V with an ultra-low quiescent current of 0.2 μA maximum at 85 °C. The device features very low ON resistance, specified as 0.50 Ω maximum at 4.3 V and 0.55 Ω maximum at 3.0 V or 3.6 V (at 25 °C). It provides fast switching speed with break-before-make delay times ranging from 7 ns to 28 ns depending on the supply voltage. The digital control inputs are 5 V tolerant and 1.8 V compatible across the operating voltage range. ESD protection exceeds 2 kV HBM, and latch-up performance exceeds 300 mA per JESD 17.

Feature Summary

Dual SPDT analog switch configuration with independent channel control
Ultra-low power dissipation suitable for portable applications
Low ON resistance ensuring minimal signal attenuation
Integrated ESD protection circuits for static discharge immunity

Applications

Portable battery-powered equipment
Bus switching and multiplexing/demultiplexing
Signal routing in communication systems

Procurement Notes

Verify the component status before procurement as the base model STG5223 is listed as obsolete in some sources. Confirm that the QFN10 package dimensions match the design footprint requirements. Ensure the ordering suffix corresponds to the tape and reel packaging format required for automated assembly processes.

Selection Notes

Select this component when designing low-voltage systems requiring dual signal path switching. Consider the specific ON resistance values at the target operating voltage to ensure signal integrity. Verify that the control logic levels align with the 5 V tolerant input specifications. Evaluate the thermal dissipation capabilities if operating near the maximum temperature limits.

Part Context

The STG5223 belongs to STMicroelectronics' family of low voltage analog switches. It utilizes C2MOS technology to achieve high speed and low power consumption. The device is designed to replace older discrete switching solutions in compact portable electronics where space and energy efficiency are critical constraints.
