MAX306

19-0270; Rev 0; 8/94 Precision, 16-Channel/Dual 8-Channel, High-Performance, CMOS Analog Multiplexers _______________General Description The MAX306/MAX307 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100 Ω ), which is matched to within 5 Ω between channels and remains flat over the specified analog signal range (7Ω max). They also offer low leakage over temperature (I NO(OFF) less 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 10pC) 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. ____________________________Features o Guaranteed On-Resistance Match Between Channels, <5Ω Max o Low On-Resistance, <100Ω Max o Guaranteed Flat On-Resistance over Specified Signal Range, 7Ω Max o Guaranteed Charge Injection, <10pC o INO(OFF) Leakage <2.5nA at +85°C o ICOM(OFF) Leakage <20nA at +85°C o ESD Protection >2000V o Plug-In Upgrade for Industry-Standard ...
