The MAX308/MAX309 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100Ω), which is matched to within 5Ω between channels and remains flat over the specified analog signal range (7Ω max). They also offer low leakage over temperature (NO-off leakage current less than 5nA at +85°C) and fast switching speeds (transition time less than 250ns). The MAX308 is a single-ended 1-of-8 device, and the MAX309 is a differential 2-of-4 device.

The MAX308/MAX309 are fabricated with Maxim's improved 44V silicon-gate process. Design improvements yield extremely low charge injection (less than 10pC) and guarantee electrostatic discharge protection greater than 2000V.

These muxes operate with a single +5V to +30V supply or bipolar ±5V to ±20V supplies, while retaining TTL/CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading. These improved parts are plug-in upgrades for the industry-standard DG408, DG409, DG508A, and DG509A.
