故障保护, 高压信号线保护器, 9 V至36 V, NSOIC-8

The is a fault protected, high voltage signal line protector in 8 pin NSOIC package. This multiple, two terminal signal line protector is pin-compatible with industry standard, this new circuit protector feature fault protected inputs & rail to rail signal handling capability. Input pins are protected from overvoltage faults up to ±36V with power on or ±40V with power off. During a fault condition input terminal becomes an open circuit and only nanoamperes of leakage current flow from source but switch output OUT_ furnishes typically 19mA from appropriate polarity supply to load. This ensures unambiguous rail to rail outputs when a fault begins & ends. It contains three independent protectors, can protect both unipolar & bipolar analogue signals using either unipolar +9V to +36V or bipolar ±8V to ±18V power supplies. It has no logic control inputs and designed to be always on when the supplies are on. It is used in data acquisition systems & redundant/
