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.
