The Intersil ISL84467 device is a low ON-resistance, low 
voltage, bidirectional, Quad SPDT (Dual DPDT) analog 
switch designed to operate from a single +1.65V to +4.5V 
supply. Targeted applications include battery powered 
equipment that benefit from low rON (0.39Ω) and fast 
switching speeds (tON = 33ns, tOFF = 16ns). The digital logic 
input is 1.8V logic-compatible when using a single +3V supply. 
With a supply voltage of 4.2V and logic high voltage of 2.85V 
at both logic inputs, the part draws only 12µA max of ICC 
current.
Cell phones, for example, often face ASIC functionality 
limitations. The number of analog input or GPIO pins may be 
limited and digital geometries are not well suited to analog 
switch performance. This part may be used to “mux-in” 
additional functionality while reducing ASIC design risk. The 
ISL84467 is offered in small form factor package, alleviating 
board space limitations.
The ISL84467 consists of four SPDT switches. It is configured 
as a dual double-pole/double-throw (DPDT) device with two 
logic control inputs that control two SPDT switches each. The 
configuration can be used as a dual differential 2-to-1 
multiplexer/demultiplexer
