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.
