FSA1156P6X – FSC

The FSA1156P6X, manufactured by Fairchild Semiconductor (FSC), is a single-pole single-throw normally-open (SPST-NO) analog switch fabricated in a sub-micron CMOS process. It is housed in an SC-88 (also known as a SOT-363) surface-mount package. The device features a typical on-resistance (R_ON) of 900 milliohms, making it suitable for low-voltage signal switching applications where minimal signal attenuation is required. The switch is designed for operation with a single supply voltage, typically in the range of 1.65V to 5.5V. Its low on-resistance minimizes insertion loss and distortion, while the small package size allows for high-density board layouts. The FSA1156P6X is commonly used in portable devices for audio and data signal routing, providing a compact and efficient switching solution.
