Electrostatic Discharge (ESD) Precautions

When handling this Silicon-on-Sapphire device, observe the

same precautions that you would use with other ESD-

sensitive devices. Although this device contains circuitry to

protect it from damage due to ESD, precautions should be

taken to avoid exceeding the specified rating.

Exposed Solder Pad Connection

The exposed solder pad on the bottom of the package must

be grounded for proper device operation.

Latch-Up Avoidance

Unlike conventional CMOS devices, Silicon-on-Sapphire

devices are immune to latch-up.

Switching Frequency

The SP43602 has a maximum 25 kHz switching rate.

Switching rate is defined to be the speed at which the DSA

can be toggled across attenuation states.

Exceeding absolute maximum ratings may cause permanent

damage. Operation should be restricted to the limits in the

Operating Ranges table. Operation between operating range

maximum and absolute maximum for extended periods may

reduce reliability.

Moisture Sensitivity Level

The Moisture Sensitivity Level rating for the SP43602 in the

24-lead 4x4 QFN package is MSL1.
