NC7SB3157P6X SPDT Analog Switch IC 1 Circuit 2:1 15Ohm SC-88
The NC7SB3157P6X from onsemi is a high-performance, single-pole double-throw (SPDT) analog switch fabricated in advanced CMOS technology, packaged in an ultra-miniature SC-70-6/SOT-363 package. This IC is specifically engineered for portable and space-constrained applications where board real estate is at a premium. It operates from a wide single supply voltage range of 1.65V to 5.5V, making it perfectly suited for interfacing between components of different voltage levels in mixed-signal systems, such as those found in battery-powered devices, while ensuring minimal signal path degradation and robust performance.
Key Features and Applications
This device stands out for its exceptionally low on-resistance (typically 4.5Ω at 3.0V VCC) and remarkably flat on-resistance characteristics across the input signal range, which is critical for preserving signal integrity in low-voltage audio and data paths. It features a high bandwidth exceeding 200MHz, making it suitable for switching high-speed digital signals like USB or data buses. The NC7SB3157P6X boasts a very low quiescent current and is characterized by its minuscule package, which is among the smallest available for this function. It is designed for break-before-make switching action and offers TTL/CMOS compatible control inputs for seamless integration with microcontrollers and FPGAs.
The NC7SB3157P6X is ideal for a vast array of portable and compact electronics, including smartphones, tablets, wearables, and digital cameras, where it is used for functions like audio jack switching, headset detection, signal gating, and peripheral connectivity (e.g., USB 1.1/2.0 switching). Its wide voltage range and high bandwidth also make it a perfect component for routing signals in industrial and communication modules, data acquisition systems for channel selection, and in any design requiring a tiny, low-loss, signal-path switch to enable multiple functional configurations.
