The MAX358 and MAX359 devices are 8‑channel single‑ended and 4‑channel differential fault‑protected analog multiplexers. They use a series N‑channel, P‑channel, N‑channel structure that limits fault currents to nanoamperes and can tolerate continuous over‑voltage up to +35 V.
The parts operate from +4.5 V to +18 V supplies, have TTL/CMOS compatible digital inputs (0.8 V low, 2.4 V high), and consume less than 2 mW typical power. Ordering information, pin configurations, and detailed electrical characteristics are provided for multiple package options.
| Supply Voltage Range | +4.5 V to +18 V |
|---|---|
| Continuous Overvoltage Rating | +35 V |
| Power Dissipation (typical) | < 2 mW |
It limits fault currents to nanoamp leakage and can tolerate continuous over‑voltage up to +35 V, protecting both the device and connected sensors.
Typical power dissipation is less than 2 mW.
