USB 2.0 High-Speed/UART Dual SP3T (Dual 3 to 1
Multiplexer)
ISL54216
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.
