Sep 27, 2010 USB 2.0 High-Speed/UART Dual SP3T (Dual 3 to 1 Multiplexer)
The Intersil ISL54216 is a single supply dual SP3T
analog switch that operates from a single supply in
the range of 2.7V to 4.6V. It was designed to
multiplex between three different differential data
sources, allowing the multiplexing of USB 2.0 high
speed and/or UART data signals through a common
headphone connector in Personal Media Players and
other portable battery powered devices.
The switch channels have very low ON capacitance
and high bandwidth to pass USB high speed signals
(480Mbps) with minimal edge and phase distortion
and can swing rail-to-rail to pass UART and full-speed
USB signals.
The ISL54216 is available in a tiny 12 Ld
2.2mmx1.4mm ultra-thin QFN and 12 Ld 3mmx3mm
TQFN packages. It operates over a temperature range
of -40°C to +85°C. Related Literature Technical Brief TB363 “Guidelines for Handling and
