Precision, 8-Channel/Dual 4-Channel, High-Performance, CMOS Analog Multiplexers
_______________General Description
The MAX308/MAX309 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less 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 leakage over temperature (NO-off leakage current less than 5nA at +85°C) and fast switching speeds (transition time less t h a n 250ns). The MAX308 is a single-ended 1-of-8 device, and the MAX309 is a differential 2-of-4 device. T h e 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 o r 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 industrystandard DG408, DG409, DG508A, and DG509A.

Note 1:
Signals on NO, COM, EN, A0, A1, or A2 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.
