PC74HCT259TSMD PC74HCT259TSMD PC74HCT259TSMD Price The MAX4843-MAX4846 0vervoltage protection con- trollers protect low-voltage systems against high-voltage faults of up t0 28V. When the input voltage exceeds the overvoltage threshold, these devices turn off a low-cost, external n-channel FET(s) to prevent damage to the pro- tected components. An internal charge pump eliminates the need for external capacitors and drives the FET gate for a simple, robust solution. PC74HCT259TSMD PC74HCT259TSMD PC74HCT259TSMD on stock The Machine Model for ESD testing uses a 200pF stor- age capacitor and zero-discharge resistance. It mimics the stress caused by handling during manufacturing and assembly. Of course, all pins (not just RS-232 inputs and outputs) require this protection during man- ufacturing. Therefore, the Machine Model is less rele- vant to the l/0 ports than are the Human Body Model and IEC1000-4-2.
