Shutdown mode is enabled by connecting all control pins to logic Functional Description low. This mode reduces the overall current consumption of the The SKY13385-460LF includes an internal negative voltage device to 5 A, typical. To prevent the switch from accidentally generator and decoder that eliminate the need for external DC entering shutdown mode during switching, caution must be taken blocking capacitors on the RF ports. No external components are to avoid having all three control signals (V1, V2, and V3) set to required for proper operation. DC decoupling capacitors may be logic low for more than 500 ns. When exiting shutdown mode, the added on the VDD and control lines if necessary. switch has a 25 s startup time before switching occurs. Switching is controlled by three control voltage inputs: V1, V2, and V3. Depending on the logic voltage level applied to the control pins, the RFC (RF common) pin is connected to one of three Electrical and Mechanical Specifications switched RF outputs (J1, J2, or J3) through a low insertion path, The absolute maximum ratings of the SKY13385-460LF are while the path between the RFC pin and the other RF pins is in a provided in Table 2.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. Note 2: Any bias voltage applied to the V1, V2, or V3 pins may damage the device if there is no bias voltage also present on the VDD pin. Maximum control voltage cannot exceed VDD. CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
