TSZ182

TSZ182 is a high-performance analog switch manufactured by STMicroelectronics, designed for precise signal routing in mixed-signal and power management applications. It features low on-resistance (typically 1.5 Ω at VDS = 0 V) and ultra-low leakage current (less than 1 nA), ensuring minimal signal distortion and high efficiency in sensitive circuits. The device operates from a supply voltage range of 1.65 V to 5.5 V, making it compatible with both low-voltage digital systems and higher-voltage analog interfaces. This monolithic CMOS switch integrates two independent channels in a single package, offering dual-channel functionality ideal for multiplexing, demultiplexing, or bidirectional signal control. Its logic-level compatibility allows direct interfacing with standard CMOS and TTL inputs, simplifying system design without requiring external level-shifting components. Additionally, the TSZ182 includes built-in ESD protection and robust latch-up immunity, enhancing reliability in harsh electrical environments. The switch exhibits excellent linearity and fast switching speed—turn-on time under 100 ns and turn-off time around 50 ns—making it suitable for high-frequency signal routing in audio, sensor, and data acquisition systems. It maintains stable performance over temperature ranges from –40 °C to +125 °C, supporting operation in industrial and automotive environments where thermal stability is critical. Applications include portable medical devices, battery-powered instrumentation, automotive infotainment systems, and consumer electronics such as smartphones and tablets. In these contexts, the TSZ182 enables efficient channel selection, signal isolation, and power-saving modes by minimizing quiescent current during inactive states. Its small footprint and low power consumption also make it ideal for space-constrained and energy-sensitive designs. STMicroelectronics ensures consistent quality through rigorous testing and compliance with industry standards like AEC-Q100 for automotive-grade reliability. The component is available in compact 8-pin SO8 and TSSOP packages, facilitating easy integration into surface-mount PCB layouts. With its combination of precision, durability, and versatility, the TSZ182 serves as a reliable solution for modern electronic systems requiring accurate and efficient signal control.
