INTERSIL HI9P0546-9Z Datasheet

The HI-546, HI-547, HI-548, and HI-549 are analog multiplexers with active overvoltage protection and guaranteed rON matching. These devices allow analog input levels to exceed the power supply without damage or signal path disturbance. They feature active protection circuitry to maintain signal fidelity even under fault conditions. The analog inputs can withstand constant 70VP-P levels with ±15V supplies, while the digital inputs can sustain continuous faults up to 4V greater than either supply. The devices also provide protection against short-circuiting in case of multiplexer supply loss. The HI-546 is a single 16-channel device, the HI-547 is an 8-channel differential device, the HI-548 is a single 8-channel device, and the HI-549 is a 4-channel differential device. These devices are suitable for systems where the analog inputs come from external equipment or separately powered circuitry. They are fabricated with 44V Dielectrically Isolated CMOS technology. The HI-506/507/508/509 multiplexers are recommended for applications that do not require input overvoltage protection. For more information, refer to Application Notes AN520 and AN521. MIL-STD-883 compliant parts are available upon request for the HI-546/883.
