MAX4518/MAX4519 19-1070 Rev. 1 5/98 Precision, 4-Channel/Dual 2-Channel, Low-Voltage, CMOS Analog Multiplexers General Description Features The MAX4518/MAX4519 precision, monolithic, CMOS Guaranteed On-Resistance Match analog multiplexers (muxes) offer low on-resistance Between Channels (<4 ) (less than 100), which is matched to within 4 Low On-Resistance (<100 ) between channels and remains flat over the specified Guaranteed Flat On-Resistance over Signal analog signal range (10 max). They also offer low leak- Range (<10) age over temperature (NO-off leakage current less than 2nA at +85C) and fast switching speeds (transition time Guaranteed Low Charge Injection (<5pC) less than 250ns). The MAX4518 is a 4-channel device, NO-Off Leakage Current <2nA at +85C and the MAX4519 is a dual 2-channel device. COM-Off Leakage Current <5nA at +85C The MAX4518/MAX4519 are fabricated with Maxims Electrostatic Discharge Protection >2000V low-voltage silicon-gate process. Design improvements Single-Supply Operation (+2.7V to +15V) yield extremely low charge injection (less than 5pC) and guarantee electrostatic discharge protection greater than Bipolar-Supply Operation (2.7V to 8V) 2000V. Low Power Consumption (<300W) These muxes operate with a single +2.7V to +15V supply Rail-to-Rail Signal Handling or with bipolar 2.7V to 8V supplies, while retaining TTL/CMOS-Logic Compatible CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading. Ordering Information Applications PART TEMP.

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.
