Octal Multiprotocol Switch
The Intersil ISL54230 is a multiprotocol Quad Double-Pole
Double-Throw (DPDT) analog switch that can operate from a
single +2.0V to +5.5V supply. It contains eight SPDT (Single
Pole/Double Throw) switches configured into four DPDT
blocks. Each DPDT block is independently controlled by a
logic input for Normally Open (NO) or Normally Closed (NC)
switch configuration.The part is designed for switching or
routing a combination of USB High-Speed, USB Full-Speed,
digital, and analog signals in portable battery powered
products.
The digital inputs are 1.8V logic compatible when operated
with a 2.7V to 3.6V supply. The ISL54230 has two switch
enable pins to disable certain blocks of the switch. The
ISL54230 is available in a 32 Ld TQFN 5mmx5mm package.
It operates over a temperature range of -40 to +85°C.
Applications
• Cellular/Mobile Phones
• PDA’s
