MAX4558/MAX4559/MAX4560 are low-voltage, CMOS analog ICs configured as an 8:1 multiplexer (MAX4558), a dual 4:1 multiplexer (MAX4559), and a triple single-pole/double-throw (SPDT) switch (MAX4560). Each switch is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup or damage. These CMOS devices can operate continuously from ±2V to ±6V of dual supplies or from a +2V to +12V single supply. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 1nA at +25°C or 10nA at +85°C max. All digital inputs have +0.8V to +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply or dual ±5V supplies.
The MAX4558, MAX4559, and MAX4560 are low‑voltage CMOS analog ICs that function as an 8‑to‑1 multiplexer, a dual 4‑to‑1 multiplexer, and a triple SPDT switch respectively. Each switch is protected against +15 kV electrostatic discharge (ESD) shocks and operates from dual supplies of +2 V to +6 V or a single supply of +2 V to +12 V. The devices handle rail‑to‑rail analog signals, have off‑leakage currents of only 1 nA at 25 °C, and digital inputs with logic thresholds of +0.8 V to +2.4 V.
Key electrical characteristics include a guaranteed on‑resistance of 220 Ω with a single +5 V supply (1600 Ω with dual +5 V supplies), low distortion (<0.02 % THD), and high isolation (>‑96 dB). The family is offered in 16‑lead QSOP, narrow‑SO, and plastic‑DIP packages, with ordering codes MAX4558CEE, MAX4558CSE, and MAX4558CPE among others.
