*CAUTION*
This product incorporates numerous static-sensitive components.
Always wear an ESD wrist strap and observe proper ESD handling
procedures when working with this device. Failure to observe this
precaution may result in module damage or failure.
PERFORMANCE DATA
These performance parameters
are based on module operation at
25°C from a 3.3VDC supply unless
otherwise noted. Figure 2
illustrates the connections
necessary for testing and
operation. It is recommended all
ground pins be connected to the
ground plane.
