Description
SPI clock signal.
SPI enable signal (slave select).
SPI power supply for all slave devices (1.8 V nominal).
Battery supply voltage input.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY18106-455LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
Table 4 provides the format of the 30-bit SPI_DATA signal.
Table 5 describes the values assigned to the contents of the
SPI_DATA signal.
The SKY18106-455LF can operate in one of 16 states as listed in
Table 6. When VDD is high, the switch is active and its state is
controlled as described in Table 6. The switch may also be used
in one of three modes: active, standby, and isolation. These
modes are controlled by bits [15:11] of the SPI data word.
NOTE: The SPI_VDD signal (pin 25) must be pushed high for 2 ms
before the first SPI command is sent to program the switch
within the operating temperature range (TOP).

Note 1: 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.
