Being a part of the XRT75L series, the XRT75L03DIVTR-F integrated circuit (IC) is a low on resistance Quad SPST Analog Switch (AS) incorporated an industry-standard Thin Small Outline Package (TSOP) 8-lead form factor, offering a distinct suitability to applications requiring an ultra-low-voltage switch. In this article, the field of application and working principle of the XRT75L03DIVTR-F will be discussed in more detail.

Field of application

The XRT75L03DIVTR-F is designed for a variety of Telecom and Interface applications, i.e. for switched capacitive loads, as well as for low voltage powers switching applications, analog switches that drive heavy loads and switching matrices. This allows for its deployment to a multitude usages, for instance, for USB/HDMI switching, for dynamic programming of capacitive loads, and for dynamic range extension of audio circuits. Its low-voltage switch suitability opens up a plethora of low-voltage switching usages, enabling applications requiring ‘low voltage’ switches such as USB On-the-Go (OTG) ports and ultra-low voltage circuits. The XRT75L03DIVTR-F is also engineered to provide minimal inrush current and glitch free performance, rendering it highly suitable for switching circuits and matrices with minimum disruption. Furthermore, it offers superior noise immunity and low insertion loss to midband and high frequency ranges, given its integrated SPST Quard AS. Its Ultra-low RDS(ON) feature adds to its suitability to medium voltage DC application requiring low power consumptions. Thus, XRT75L03DIVTR-F has utility across a broad swath of Interface/Telecom applications that require low-voltage switching, low RDS(ON) and minimal inrush current.

Working principle

The XRT75L03DIVTR-F is a dedicated Low RDS(ON) Quad SPST Analog Switch. It focuses on providing a low RDS(ON) connection with minimal power dissipation. In each logic control pin, an integrated Electrostatic Discharge (ESD) protection device allows for ESD protection up to ±8kV HBM voltage. The power supply voltage used in the XRT75L03DIVTR-F ranges from 0.7V to 4.2V, further enabling its deployment to low-voltage switching applications. A slot-by-slot feature allows for operation efficiency at the most optimal power level, thus enhancing its overall power performance. When in power-on, the XRT75L03DIVTR-F’s 4-SPST ASs provide low RDS(ON) connection with a maximum of 0.95Ω between the inputs, thus allowing for minimal power dissipation. The XRT75L03DIVTR-F also offers a low power-mode, thus allowing applications to be switched off when not in operation and saving power states; when in power-off mode, all circuitry is disabled, except for the logic pins.

The XRT75L03DIVTR-F is a highly efficient and low power consuming IC that can be used in a variety of Interface/Telecom applications. Its versatility, low-voltage switch, low RDS(ON) and minimal inrush current make it ideal for use in these applications. Its integrated Electrostatic Discharge (ESD) protection devices also allow for greater protection of the signal on both sides. Its slot-by-slot feature allows for a flexible power performance and its power-off mode feature allows for an even lower power consumption. All in all, the XRT75L03DIVTR-F presents itself to be a great versatile tool for a variety of Interface/Telecom applications.
