The MAX4051/4052/4053 series are low-voltage CMOS analog integrated circuits configured as an 8-channel multiplexer (MAX4051), two 4-channel multiplexers (MAX4052) and three single-pole/double-throw (SPDT) switches (MAX4053). A-suffix parts are fully characterized for on-resistance match, on-resistance flatness, and low leakage. These CMOS devices can operate continuously with dual power supplies ranging from ±2.7 V to ±8 V or a single supply between +2.7 V and +16 V. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0.1 nA at +25°C or 5 nA at +85°C (MAX4051A/4052A/4053A). All digital inputs have 0.8 V to 2.4 V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±5 V or a single +5 V supply.
The MAX4051, MAX4052 and MAX4053 devices are low‑voltage CMOS analog ICs configured as an 8‑channel multiplexer, two 4‑channel multiplexers, and three SPDT switches respectively. They operate from dual supplies (±2.7 V to ±8 V) or a single supply (+2.0 V to +16 V) and handle rail‑to‑rail analog signals.
Key features include 100 Ω guaranteed on‑resistance with ±5 V supplies, on‑resistance matching between channels (6 Ω to 12 Ω), off‑leakage as low as 0.1 nA at 25 °C, TTL/CMOS‑compatible digital inputs, low distortion (<0.04 %), and high off‑isolation (<‑90 dB). The datasheet provides absolute maximum ratings, detailed electrical characteristics, pin configurations, and package information.
