Electrostatic Discharge (ESD) Precautions

When handling this UltraCMOS™ 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

rate specified in Table 4.

Exposed Solder Pad Connection

The exposed solder pad on the bottom of the package

must be grounded for proper device operation.

Notes: 5. For improved RF performance these No Connect pins can

be connected to RF ground.

6. Pins can either be grounded directly or through coupling

capacitors

7. Pin can either be grounded or No Connect

The standard 3V or 5V CMOS control logic is

independent of supply voltage.
