19-1064; Rev 1; 1/07
Low-Voltage, Dual-Supply, SPST,
CMOS Analog Switches
General Description
____________________________Features
ꢀ Available in SOT23-5 Package
ꢀ Dual-Supply Operation from 1V to 6V
The MAX4503/MAX4504 are low-voltage, dual-supply,
single-pole/single-throw (SPST), CMOS analog switch-
es. The MAX4503 is normally open (NO). The MAX4504
is normally closed (NC).
ꢀ Guaranteed On-Resistance:
250Ω with 5V Supplies
ꢀ Guaranteed Low Off-Leakage Currents:
1nA at +25°C
These CMOS switches can operate continuously with
dual supplies between ±±.ꢀ and ±ꢁꢀ. ꢂach switch can
handle rail-to-rail analog signals. The off-leakage cur-
rent is only ±nA at +25°C or ±0nA at +85°C.
10nA at +85°C
ꢀ Guaranteed Low On-Leakage Currents:
2nA at +25°C
The digital input is CMOS-logic compatible when using
±5ꢀ supplies. A uniꢃue logic input architecture allows
this even though the parts have no ground pin.
20nA at +85°C
ꢀ Guaranteed Low Charge Injection: 10pC Max
For single-supply operation, use the MAX450±/
MAX4502, which are pin-for-pin eꢃuivalents.
ꢀ Fast Switching Speed: t
= 150ns, t
= 100ns
