Description
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 36 ball 2.5mmx2.5mm WLCSP or a 32 Ld TQFN 5mmx5mm package. It operates over a temperature range of -40 to +85°C.
