Ultra Low ON-Resistance, +1.65V to +4.5V, Single Supply, Quad SPDT (Dual DPDT) Analog Switch
The Intersil ISL8499 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 (0.24) and fast switching speeds (tON = 15ns, tOFF = 13ns). 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 10uA 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 ISL8499 is offered in small form factor packages, alleviating board space limitations. The ISL8499 consists of four SPDT switches. It is configured as a dual double-pole/double-throw (DPDT) device with tw
o logic control inputs that control two SPDT switches each. The configuration can be used as a dual differential 2-to-1 multiplexer/demultiplexer. The ISL8499 is pin compatible with the STG3699 and DG2799.
