_______________General Description

The MAX4514/MAX4515 are single-pole/single-throw

(SPST), CMOS, low-voltage, single-supply analog

switches with very low switch on-resistance. The

MAX4514 is normally open (NO). The MAX4515 is nor-

mally closed (NC).

These CMOS switches can operate continuously with a

single supply between +2V and +12V. Each switch can

handle rail-to-rail analog signals. The off-leakage cur-

rent maximum is only 1nA at +25°C or 20nA at +85°C.

All digital inputs have 0.8V to 2.4V logic thresholds,

ensuring TTL/CMOS-logic compatibility when using a

+5V supply.

For pin-compatible parts for use with dual supplies, see

the MAX4516/MAX4517.

MAX4514/MAX4515 Low-Voltage, Low-On-Resistance, SPST, CMOS Analog Switches __________Applications Information Power-Supply Considerations The MAX4514/MAX4515 construction is typical of most CMOS analog switches, except that they have only two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog voltage limits. Reverse ESD-protection diodes are internally connected between each analog-signal pin and both V+ and GND.
