STG4159BJR

Overview

The STG4159BJR is a high-speed CMOS low-voltage single analog SPDT switch fabricated in silicon gate C2MOS technology. It operates from 1.65V to 4.8V with separate supply voltage for the switch and control pin. The device features low ON-resistance, ranging from 0.30Ω max at 4.3V to 0.40Ω max at 2.25V. It includes break-before-make functionality and robust ESD protection rated at 10kV contact discharge on the common channel. Quiescent supply current is 0.2µA max at 85°C. The component is housed in a Flip-Chip7 package.

Feature Summary

Single-pole dual-throw (SPDT) switching architecture with independent channels and a common port
Separate logic supply voltage (VL) distinct from the analog switch supply voltage (VCC)
Integrated break-before-make delay to prevent signal shorting during state transitions
High electrostatic discharge immunity across all pins and ports

Applications

Portable electronic equipment requiring low power consumption
Signal routing in multiplexer or demultiplexer configurations
Battery-powered systems utilizing wide operating voltage ranges

Procurement Notes

Verify the specific ordering suffix BJR to confirm tape and reel packaging requirements. Confirm that the component status is obsolete before initiating procurement actions. Ensure compatibility with the Flip-Chip7 footprint dimensions and soldering profiles specified in the mechanical data section of the datasheet.

Selection Notes

Select this component when a single-channel analog switch with separate logic and power supplies is required. Evaluate the ON-resistance specifications against the maximum allowable voltage drop for the target application. Consider the break-before-make timing characteristics if signal integrity during switching transitions is critical.

Part Context

The STG4159BJR belongs to the STG4159 family of low-voltage analog switches manufactured by STMicroelectronics. This series utilizes C2MOS technology to achieve high speed and low power dissipation. The part is designed for applications where space constraints and energy efficiency are primary design drivers.
