  DESIGN INFORMATION Tiny MSOP Dual Switch Driver
  is SMBus Controlled
  Introduction by Peter Guan VCC
  2.7V TO 5.5V The LTC1623 SMBusв„ў switch
  controller offers an inexpensive,
  space-saving alternative for controlling peripherals in today’s complex
  portable computer systems. Pin-topin connections between the system
  controller and each peripheral device
  not only result in complicated wiring,
  but also limit the number and type of
  peripheral devices connected to the
  system controller. Using the SMBus
  architecture, the LTC1623 eliminates
  these problems by requiring only two
  bus wires and allowing easy upgrades
  and additions of new peripherals. 10ВµF
