The Intersil ISL84581 device contains precision, bidirectional, analog switches configured as an 8-to-1 multiplexer/demultiplexer. It was designed to operate from a single +2V to +12V single supply or from dual ±2V to ±6V supplies. The device has an inhibit pin to simultaneously open all signal paths. The ISL84581 has an ON-resistance of 39Ω with a dual ±5V supply and 125Ω with a single +3. 3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0. 02nA at +25°C or 0. 2nA at +85°C. All digital inputs have 0. 8V to 2. 4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a single 3. 3V or +5V supply or dual ±5V supplies. The ISL84581 is a single 8-to-1 multiplexer device.

The Intersil ISL84582 device is made of precision, bi-directional, analog switches configured as a differential 4-Channel multiplexer/demultiplexer. It is designed to operate from a single +2V to +12V supply or from a ±2V to ±6V dual supplies. The device has an inhibit pin to simultaneously open all signal paths. ON-resistance of 39Ω with a ±5V supply and 125Ω with a single +3. 3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0. 02nA at +25°C or 0. 2nA at +85°C. All digital inputs have 0. 8V to 2. 4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a single 3. 3V or +5V supply or dual ±5V supplies. The ISL84582 is a differential 4-to-1 multiplexer device.

The Intersil ISL84715 and ISL84716 devices are low ON-resistance, low voltage, bidirectional, single pole/single throw (SPST) analog switches designed to operate from a single +1. 65V to +3. 6V supply. Targeted applications include battery powered equipment that benefit from low RONresistance, excellent RONflatness, and fast switching speeds (tON= 9ns, tOFF= 5ns). The digital logic input is 1. 8V CMOS compatible when using a single +3V supply. 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 family of parts may be used to switch in additional functionality while reducing ASIC design risk. The ISL8471X are offered in a 5 lead SC70 package, alleviating board space limitations. The ISL84715 has one normally open (NO) switch and ISL84716 has one normally closed (NC) switch.
