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.

NOTES:
11. Vlogic = Input voltage to perform proper function.
12. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this
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
range.
15. Limits established by characterization and are not production tested.
16. rON matching between channels is calculated by subtracting the channel with the highest max rON value from the channel
with lowest max rON value, between 1D+ and 1D- or between 2D+ and 2D- or between 3D+ and 3D-.
