ONSEMI FSA3357K8X Analog Switch

The FSA3357 is a high-performance, low-voltage SP3T analog switch designed for both analog and digital applications. Fabricated with advanced CMOS technology, it features high-speed enable/disable times, low On Resistance (< 90Ω at 3.3V), and a broad operating voltage range from 1.65V to 5.5V. Its break-before-make circuitry prevents signal disruption during switch transitions. The device is available in space-efficient 8-lead MicroPak and US8 packages, with overvoltage control input tolerance up to 7.0V, making it suitable for space-constrained, high-speed switching applications like cell phones, PDAs, and video equipment.
