This product has been designed for switching audio signals in applications such as cell phones and portable media players. The ultra-low 0.4Ω impedance, sub-μ current consumption, and 1.65V to 4.3V operating voltage range makes this product ideal for battery-powered applications. The F5157 also features bi-directional operation and break-before-make functionality. This device is fully specified for operation at 1.8V, 2.5V, and 3.3V. growing number of applications require the voltage applied to the select input to be lower than the applied. Under this condition, most switches would typically consume over 100μ of current. This would be an unacceptable level for battery-powered applications. The F5157 is designed to minimize current consumption under this condition. The I CCT is specified for <12μ under a worst-case condition of = 4.3V and V IN = 1.8V.

3 bsolute Maximum Ratings tresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. ymbol Parameter Min.
