The MAX4524 and MAX4525 are low‑voltage, single‑supply CMOS analog switches. MAX4524 functions as a 4‑channel multiplexer/demultiplexer, while MAX4525 provides a double‑pole/double‑throw (DPDT) switch. Both devices include an inhibit input that can open all signal paths simultaneously and operate from a single supply of +2 V to +12 V.
The datasheet details electrical characteristics such as on‑resistance, leakage currents, logic thresholds, and timing parameters, as well as package options, ordering information, and test circuit diagrams for designers.
| Supply Voltage Range | +2 V to +12 V |
|---|---|
| On‑Resistance (5 V) | 200 Ω |
| On‑Resistance (3 V) | 500 Ω |
| Off‑Leakage Current (25 °C) | 2 nA |
| Off‑Leakage Current (85 °C) | 20 nA |
| Logic Input Thresholds | 0.8 V to 2.4 V |
They operate from a single supply of +2 V to +12 V.
The on‑resistance is 200 Ω at a +5 V supply.
The off‑leakage current is 2 nA at +25 °C.
Digital inputs accept logic levels from 0.8 V to 2.4 V.
