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”

on page 1.

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
