The device Features ultra-low RON of 0.8Ω (maximum) at 4.5V VCC and operates over the wide VCC range of 1.65V to 5.5V. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The FSA839 interfaces between the low-voltage ASIC and regular audio amplifiers and CODECs operating up to a 5.5V supply range. The control circuitry allows for 1.8V (typical) signals on the control pin (Sel). - HBM per JESD22-A114, I/O to GND: CDM per JESD22-C101: IEC61000-4-2 Contact / Air: 8k V 500V IMPORTANT NOTE: For additional performance information, please contact analogswitch@fairchildsemi.. 8k V / 15k V Applications - Cellular Phone - Portable Media Player - PDA ..
