MAX4781/MAX4782/MAX4783 are high-speed, low-voltage, low on-resistance, CMOS analog multiplex- ers/switches configured as an 8-channel multiplexer (MAX4781), two 4-channel multiplexers (MAX4782), and three single-pole/double-throw (SPDT) switches (MAX4783).
The MAX4781, MAX4782, and MAX4783 are CMOS analog multiplexers/switches that operate from a single supply of +1.6 V to +3.6 V. They feature low on‑resistance (0.7 Ω at +3 V), fast switching (11 ns turn‑on, 4 ns turn‑off) and low power consumption (<3 µW).
These devices are offered in 16‑pin thin QFN (3 mm × 3 mm) and 16‑pin TSSOP packages and are pin‑compatible with the industry‑standard 74HC4051/4052/4053 families. Typical applications include battery‑operated equipment, low‑voltage data‑acquisition systems, and audio signal routing.
