MAX4510EUA datasheet
General Deion
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) becomes an open circuit; only nanoamperes of leakage current flow from the fault source， and the switch output (COM) furnishes up to 13mA 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 160? max. The off-leakage current is only 0.5nA at +25°C and 10nA 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 compatibility when using ±15V or a single +12V supply. The MAX4510/ MAX4520 are available in 6-pin SOT23 and 8-pin μMAX packages.

Note 3: Algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 4: Leakage parameters are 100％ tested at maximum-rated hot temperature and guaranteed by correlation at TA = +25°C.
Note 5: SOT packages are 100％ tested at +25°C. Limits at the maximum-rated temperature are guaranteed by design and corre-
lation limits at +25°C. Leakage tests for the SOT package are typical only.
Note 6: NC and NO pins are fault protected. Signals on NC or NO exceeding -36V to +36V may damage the device. These limits
apply with power applied to V+ or V-， or ±40V with V+ = V- = 0.
Note 7: Guaranteed by design.
Note 8: Off isolation = 20log10 [ VCOM / (VNC or VNO) ]， VCOM = output， VNC or VNO = input to off switch.
Note 9: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
