MAX4520 Datasheet | Maxim Integrated

Description The MAX4510/MAX4520 single-pole/single-throw (SPST), fault-protected analog switches feature a fault-protected input and Rail-to-Rail® signal-handling capability. The normally open (NO) and normally closed (NC) terminals are protected from overvoltage faults up to 36V during power-on and 44V with power off. During a fault condition, the switch input terminal (NO or NC) bees an open circuit; only nanoamperes of leakage current flow from the fault source, and the switch output () furnishes up to 13m A of the appropriate polarity supply voltage to the load. This ensures unambiguous rail-to-rail outputs when a fault begins and ends. On-resistance is 160Ω max. The off-leakage current is only 0.5n A at +25°C and 10n A at +85°C. The MAX4510 is a normally closed switch, while the MAX4520 is a normally open switch. These CMOS switches operate with dual power supplies ranging from ±4.5V to ±20V or a single supply between +9V and +36V. The digital input has +0.8V and +2.4V logic thresholds, ensuring both TTL- and CMOS-logic patibility when using ±15V or a single +12V supply. The MAX4510/ MAX4520 are available in 6-pin SOT23 and 8-pin µMAX packages.
