MAX382/MAX384 are low-voltage, CMOS, 1-of-8 and dual 4-channel muxes with latchable digital inputs. They feature low-voltage operation from a +2.7V to +16.5V single supply and from ±3V to ±8V dual sup- plies. Pin compatible with the DG428/DG429, these muxes offer low on-resistance (100Ω max) matched to within 4Ω max between channels. Additional features include off leakage less than 2.5nA at +85°C and guar- anteed low charge injection (10pC max). ESD protec- tion is greater than 2000V per Method 3015.7.
The MAX382 and MAX384 are low‑voltage CMOS multiplexers offering 1‑of‑8 (MAX382) or dual 4‑channel (MAX384) switching with latchable digital inputs. They operate from a +2.7 V to +16.5 V single supply or ±3 V to ±8 V dual supplies, feature low on‑resistance (100 Ω max) and tight channel‑to‑channel matching (4 Ω max), and provide low leakage (2.5 nA at +85 °C) and low power consumption (<300 µW).\n\nThese devices are suitable for battery‑operated systems, audio signal routing, low‑voltage data‑acquisition, sample‑and‑hold circuits, and automatic test equipment. The datasheet includes pin descriptions, electrical characteristics, typical operating curves, timing diagrams, and ordering information for various package options.
