Description
The Intersil ISL54222A is a single supply dual 2:1 multiplexer that can operate from a single 1.8V to 3.3V supply. It contains two SPDT (Single Pole/Double Throw) switches configured as a DPDT. The part was designed for switching or routing of USB High-Speed signals and/or USB Full-speed signals in portable battery powered products.
The 4.4Ω switches can swing rail-to-rail and were specifically designed to pass USB full speed data signals that range from 0V to 3.3V and USB high-speed data signals that range from 0V to 400mV with a single supply as low as 1.8V. They have high bandwidth and low capacitance to pass USB high speed data signals with minimal distortion.
The digital logic inputs are 1.8V logic compatible when operated with a 1.8V to 3.3V supply. The ISL54222A has an output enable pin to open all the switches and put the part in a low power state.
The ISL54222A is available in 10 Ld 1.8mmx1.4mm μTQFN, 10 Ld 2.1mmx1.6mm μTQFN, 10 Ld TDFN and 10 Ld MSOP packages. It operates over a temperature range of -40°C to +85°C.
The price listed is the manufacturer's suggested retail price for quantities of 1K units. However, prices in today's market are fluid and may change without notice.
