FSA4157P6X

FSA4157P6X Description

The FSA4157P6X is a low-voltage, single-pole double-throw (SPDT) analog switch from Fairchild (now onsemi), designed for high-performance signal routing in compact, power-sensitive applications. This monolithic CMOS IC operates with a 1.65V to 5.5V single supply, making it ideal for portable and battery-powered devices. With an ultra-low supply current of 500nA (max) and fast switching times (35ns On, 15ns Off), it ensures efficient power management and rapid signal processing. The device features a minimal on-resistance of 1.15Ω (max) and supports 200mA continuous current, ensuring minimal signal distortion. Packaged in a 2mm x 1.25mm x 1mm SMD form factor, it is optimized for space-constrained designs while complying with RoHS standards.
