6. Pin Configuration

Standard 16-Pin or 8-Pin SOP (M) Packages

7. 8-Pin Options

The standard 16-pin package allows complete control of all configurable features. Some reduced

function 8-pin versions are also available.

For high-volume applications additional customized 8-pin devices can be produced. SWEN, SEL0

and SEL1 pins are internally bonded to reduce the pin count. Pin 6 may be configured as either

SHUT or WAKEB.
