DATASHEET
ISL54233
Wideband Differential 3:1 Multiplexer
The Intersil ISL54233 is a single supply differential 3 to 1
multiplexer 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 data signals, UART data signals and digital
video through a common headphone connector in Personal
Media Players and other portable battery powered devices.
The switch channels have low ON capacitance and high
bandwidth (1.6GHz) to pass USB high speed signals (480Mbps)
and digital video signals with minimal edge and phase distortion
and can swing rail-to-rail to pass UART and full-speed USB
signals.
All channels of the multiplexer can be turned OFF (disabled) by
driving the C0 and C1 logic pins to the low state.
The ISL54233 is available in a tiny 12 Ld 2.2mmx1.4mm
ultra-thin QFN and 12 Ld 3mmx3mm TQFN package. It operates
over a temperature range of -40°C to +85°C.

NOTES:
11. V
logic
= 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. r
