Typical Application
Pin Configuration
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
