The MAX4534/MAX4535 are fault-protected multiplexers operating with ±4.5V to ±20V dual supplies or a +9V to +36V single supply. These multiplexers feature fault-protected inputs, rail- to-rail signal-handling capability, and overvoltage clamping at 150mV beyond the rails.
The MAX4534 (single 4‑to‑1) and MAX4535 (dual 2‑to‑1) are fault‑protected, high‑voltage analog multiplexers that operate from ±4.5 V to ±20 V dual supplies or +9 V to +36 V single supply. They feature rail‑to‑rail signal handling, TTL/CMOS‑compatible inputs, and over‑voltage clamping.
The devices provide ±40 V fault protection when power is off and ±25 V protection when power is on, with on‑resistance up to 400 Ω and channel‑to‑channel resistance matching within 10 Ω. Detailed electrical characteristics, pin configurations, and typical operating curves are included.
| On‑Resistance (max) | 400 Ω |
|---|---|
| Fault‑Protection Voltage (power off) | ±40 V |
| Supply Voltage Range | ±4.5 V to ±20 V (dual) or +9 V to +36 V (single) |
| Logic Input Thresholds | TTL compatible |
The on‑resistance is specified up to 400 Ω.
The devices protect against up to ±40 V overvoltage when power is off.
They operate from ±4.5 V to ±20 V dual supplies or from +9 V to +36 V single supply.
Yes, all digital inputs have TTL logic thresholds, making them TTL/CMOS compatible.
