FSA266K8X

The FSA266K8X is a dual single-pole/single-throw (SPST) analog switch manufactured by Marvell Technology Group Ltd. This device is designed for high-speed applications, operating over a wide supply voltage range of 1.65V to 5.5V. It features a low typical on-resistance of 13.5Ω and a bandwidth of 300 MHz, making it suitable for both analog and digital signal routing.

The FSA266K8X is fabricated using advanced sub-micron CMOS technology, ensuring high speed enable and disable times. The device is organized as two independent switches, each controlled by a CMOS-compatible enable (OE) input. When OE is HIGH, the switch is ON, connecting Port A to Port B. When OE is LOW, the switch is OPEN, creating a high-impedance state between the ports. The enable inputs can tolerate voltages up to 5.5V, independent of the supply voltage.

This analog switch is housed in a space-saving US8 surface mount package, specifically a VSSOP-8. It operates within a temperature range of -40°C to 85°C. The device is RoHS compliant and lead-free.

Key electrical characteristics include a typical supply current of 1µA and a maximum power dissipation of 0.25W. The propagation delay is a maximum of 600 ps. These specifications make the FSA266K8X a versatile component for various electronic designs requiring efficient signal switching.
