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

data sheet.
13. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
14. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal
