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.

Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.
The state of the SKY13477-001A is determined by the logic
provided in Table 4.
