SKY13477-001A Block Diagram Description The SKY13477-001A is a Three-Pole, Four-Throw (3P4T) switch. Switching is controlled by an integrated GPIO interface with four control pins. Depending on the logic voltage level applied to the control pins, the following switched outputs are possible: RF1 port can be connected to the RF6 or RF5 port. A B C RF6 RF4 RF1 RF2 port can be connected to the RF7 port. 5 RF3 port can be connected to the RF4, RF5, RF6, or RF7 port. No external DC blocking capacitors are required as long as no DC voltage is applied on any RF path. The internal voltage regulator allows the VDD supply value to be within 2.45 V to 3.00 V. Logic control is 1.8 V nominal. RF5 GND1 RF2 4 RF7 GND2 RF3 3 VC3 DGND VC4 2 VDD VC1 VC2 1 S3173 Figure 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. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13477-001A are provided in Table 2. Electrical specifications are provided in Table 3. A timing diagram is provided in Figure 3 that shows the status and sequence of control lines, VDD, and the RF signal for power on and switching time specifications.
