MAX4581/MAX4582/MAX4583 are low-voltage CMOS analog ICs configured as an 8-channel multiplexer (MAX4581), two 4-channel multiplexers (MAX4582), and three single-pole/double-throw (SPDT) switches (MAX4583). These CMOS devices can operate continuously with ±2V to ±6V dual power supplies or a +2V to +12V sin- gle supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C or 5nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V or dual ±5V supplies.
The MAX4581, MAX4582, and MAX4583 are CMOS analog ICs configured as an 8‑channel multiplexer, two 4‑channel multiplexers, and three SPDT switches. They operate from dual ±2 V to ±6 V supplies or a single +2 V to +12 V supply and handle rail‑to‑rail analog signals.
Key features include ultra‑low off‑leakage (1 nA at +25 °C), on‑resistance as low as 80 Ω with ±5 V supplies, TTL/CMOS‑compatible logic thresholds (0.8 V–2.4 V), low crosstalk (< ‑96 dB), high off‑isolation (< ‑74 dB), and very low distortion (< 0.02 %). The devices are offered in multiple package types and are qualified for automotive temperature ranges.
