See Table 4. 16 GND Ground Functional Description Electrical and Mechanical Specifications The SKY13384-350LF is comprised of a CMOS decoder that enables two TTL-compatible DC lines to control four RF ports. The decoder is internally connected to a GaAs pHEMT RF switch. Depending on the logic voltage level applied to the control pins, the RFC pin is connected to one of four switched RF outputs (RF1, RF2, RF3, or RF4) by a low insertion loss path, while maintaining a high isolation path to the alternate port. The absolute maximum ratings of the SKY13384-350LF are provided in Table 2. Electrical specifications are provided in Table 3. The CMOS decoder should have VDD applied before a logic high is applied to one of the control lines. The state of the SKY13384-350LF is determined by the logic provided in Table 4. Typical performance characteristics of the SKY13384-350LF are illustrated in Figures 3 through 9. The recommended startup sequence is: 1. Apply VDD. 2. Apply VC1 and VC2 3. Apply RF input. The device must be turned off in the reverse order. 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. 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.
