Low-Voltage, SPST, CMOS Analog Switches
_________________General Description
_____________________________Features
The MAX4501/MAX4502 are single-pole/single-throw
(SPST), low-voltage, single-supply, CMOS analog
switches. The MAX4501 is normally open (NO). The
MAX4502 is normally closed (NC).
ꢀ Available in SOT23-5 and SC70-5 Packages
ꢀ +2V to +12V Single-Supply Operation
ꢀ Guaranteed On-Resistance: 250Ω at +5V
ꢀ Guaranteed Low Off-Leakage Current
1nA at +25°C
10nA at +85°C
ꢀ Guaranteed Low On-Leakage Current
2nA at +25°C
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
current is only 1nA at +25°C or 10nA at +85°C.
The digital input has 0.8V and 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V supply.
20nA at +85°C
ꢀ Low Charge Injection: 10pC
ꢀ Fast Switching Speed: t
= 75ns, t
= 50ns
