8-Pin Options

The standard 16-pin package allows complete control of all

configurable features. Some reduced function 8-pin versions

are also available, see “Ordering Information” above.

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.
