The MAX4581L/MAX4582L/MAX4583L are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4581L), two 4-channel multiplexers (MAX4582L), and three single-pole/double-throw (SPDT) switches (MAX4583L). These CMOS devices operate with a +2V to +12V single supply. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 2nA at +25°C. All digital inputs have 0.8V to 2.0V logic thresholds to ensure TTL/CMOS-logic compatibility when using a +12V supply. Applications: Audio and Video Signal Routing, Data-Acquisition Systems, Communications Circuits, Automotive DSL Modem. Features: +3V Logic-Compatible Inputs (VIH = 2.0V, VIL = 0.8V); Guaranteed On-Resistance: 80Ω with +12V Supply; Guaranteed 4Ω On-Resistance Match Between Channels; Guaranteed Low Off-Leakage Current: 2nA at +25°C; Guaranteed Low On-Leakage Current: 2nA at +25°C; +2V to +12V Supply Operation; TTL/CMOS-Logic Compatible; Low Crosstalk: -96dB (MAX4582L); High Off-Isolation: -90dB; Tiny 4mm × 4mm Thin QFN Package; Pin Compatible with Industry-Standard 74HC4051/74HC4052/74HC4053 and MAX4051/MAX4052/MAX4053.
The MAX4581L, MAX4582L, and MAX4583L are low‑voltage CMOS analog ICs from Maxim. The MAX4581L provides an 8‑channel multiplexer, the MAX4582L two 4‑channel multiplexers, and the MAX4583L three SPDT switches, all compatible with rail‑to‑rail signals.
These devices operate from a single +2 V to +12 V supply, feature 0.8 V‑2.0 V logic‑compatible inputs, 80 Ω on‑resistance, and only 2 nA off‑leakage at +25 °C. They are offered in a 4 mm × 4 mm thin QFN package and are pin‑compatible with 74HC4051/4052/4053 families.
