MAX317/MAX318/MAX319 19-0185 Rev 1 11/94 Precision, CMOS Analog Switches General Description Features The MAX317/MAX318/MAX319 are precision, CMOS, Low On Resistance <20 Typical (35 Max) monolithic analog switches. The single-pole single- Guaranteed Matched On Resistance Between throw (SPST) MAX317 is normally closed (NC), the Channels <2 SPST MAX318 is normally open (NO), and the single- pole double-throw (SPDT) MAX319 has one normally Guaranteed Flat On Resistance over Analog open and one normally closed switch. All three parts Signal Range 3 Max offer low on resistance (less than 35), guaranteed to Guaranteed Charge Injection <10pC match within 2 between channels and to remain flat over the analog signal range (3 max). They also Guaranteed Off-Channel Leakage <6nA at +85C offer low leakage (less than 250pA at +25C and less than 6nA at +85C) and fast switching (turn-on time ESD Guaranteed > 2000V per Method 3015.7 less than 175ns and turn-off time less than 145ns). Single-Supply Operation (+10V to +30V) The MAX317/MAX318/MAX319 are fabricated with Bipolar-Supply Operation (4.5V to 20V) Maxims new improved silicon-gate process. Design TTL-/CMOS-Logic Compatible improvements guarantee extremely low charge injec- tion (10pC), low power consumption (35W), and elec- Rail-to-Rail Analog Signal Handling Capability trostatic discharge (ESD) greater than 2000V.

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.
