MAXIM INTEGRATED / ANALOG DEVICES MAX367CWN Signal Line Protector

The MAX367CWN+ is an 18-pin WSOIC package signal line circuit protector designed to safeguard sensitive electronic components from voltage surges and faults. It features two-terminal protection circuits, each comprising two N-channel FETs and one P-channel FET, capable of handling voltages up to ±40V. The device is suitable for use with unipolar (4.5V to 36V) or bipolar (±2.25V to ±18V) power supplies, and provides automatic overvoltage protection during power-up, power-down, or fault conditions. It is normally on when powered and open when off, with a maximum on-resistance of 100 ohms at ±10V supplies and leakage below 1nA at +25°C. Applications include process control, hot insertion boards, data acquisition, backup systems, and automatic test equipment. Key features include a maximum supply voltage of 44V, an operating temperature range of 0°C to 70°C, eight independent symmetrical protectors, and fast, reliable overvoltage protection without the need for programming or control circuits. The signal path resistance matches within 7 ohms at +25°C.
