... ASIC design risk. The ISL84467 is offered in small form factor package, alleviating board space limitations. The ISL84467 consists of four SPDT switches 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 ...

... NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. 2 ISL84467 Truth Table LOGIC 0 1 NOTE: Logic “ ...

... External V+ Series Resistor For improved ESD and latch-up immunity, Intersil recommends adding a 100Ω resistor in series with the V+ power supply pin of the ISL84467 IC (see Figure 8). During an overvoltage transient event, such as occurs during system level IEC 61000 ESD testing, substrate currents can be ...

... Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation. The ISL84467 has been designed to minimize the supply current whenever the digital input voltage is not driven to the supply rails (0V to V+). For example, driving the device with 2.85V logic (0V to 2.85V) while operating with a 4.2V supply the device draws only 12μ ...

... High-Frequency Performance In 50Ω systems, the ISL84467 has a -3dB bandwidth of 104MHz (see Figure 22). The frequency response is very consistent over a wide V+ range, and for varying analog signal levels. An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch’ ...
