MAX308/MAX309 19-0271 Rev 2 8/02 Precision, 8-Channel/Dual 4-Channel, High-Performance, CMOS Analog Multiplexers General Description Features Guaranteed On-Resistance Match Between The MAX308/MAX309 precision, monolithic, CMOS ana- Channels, <5 Max log multiplexers (muxes) offer low on-resistance (less than 100 ), which is matched to within 5 between Low On-Resistance, <100 Max channels and remains flat over the specified analog sig- Guaranteed Flat On-Resistance over Specified nal range (7 max). They also offer low leakage over Signal Range, 7 Max temperature (NO-off leakage current less than 5nA at Guarateed Low Charge Injection, <10pC +85C) and fast switching speeds (transition time less NO-Off Leakage Current <5nA at +85C than 250ns). The MAX308 is a single-ended 1-of-8 COM-Off Leakage Current <20nA at +85C device, and the MAX309 is a differential 2-of-4 device. ESD Protection >2000V The MAX308/MAX309 are fabricated with Maxims Plug-In Upgrade for Industry-Standard improved 44V silicon-gate process. Design improve- DG408/DG409/DG508A/DG509A ments yield extremely low charge injection (less than 10pC) and guarantee electrostatic discharge protection Single-Supply Operation (+5V to +30V) Bipolar-Supply Operation (5V to 20V) greater than 2000V. Low Power Consumption, <300W These muxes operate with a single +5V to +30V supply or bipolar 5V to 20V supplies, while retaining Rail-to-Rail Signal Handling TTL/CMOS-logic input compatibility and fast switching. TTL/CMOS-Logic Compatible CMOS inputs provide reduced input loading. These Ordering Information improved parts are plug-in upgrades for the industry- standard DG408, DG409, DG508A, and DG509A.

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.
