_______________General Description
T h e MAX306/MAX307 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance ( l e s s than 100), which is matched to within 5 between channels and remains flat over the specified analog signal range (7 max). They also offer low leaka g e over temperature (I N O ( O F F ) l e s s than 2.5nA at +85°C) and fast switching speeds (tTRANS less than 250ns). The MAX306 is a single-ended 1-of-16 device, and the MAX307 is a differential 2-of-8 device. The MAX306/MAX307 are fabricated with Maxim's improved 44V silicon-gate process. Design improvements yield extremely low charge injection (less than 10 pC ) and guarantee electrostatic discharge (ESD) protection greater than 2000V. These muxes operate with a single +4.5V to +30V supply, or bipolar ±4.5V 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 industrystandard DG406, DG407, DG506A, and DG507A.

Signals on NO, COM, A0, A1, A2, A3, or EN exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current ratings.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
