Improved, Quad, SPST Analog Switches
_______________General Description
Maxim’s redesigned DG444/DG445 analog switches
now feature on-resistance matching (4max) between
switches and guaranteed on-resistance flatness over
the signal range (9max). These low on-resistance
switches conduct equally well in either direction. They
guarantee low charge injection (10pC max), low power
consumption (35µW max), and an ESD tolerance of
2000V minimum per Method 3015.7. The new design
offers lower off leakage current over temperature (less
than 5nA at +85°C).
The DG444/DG445 are quad, single-pole/single-throw
(SPST) analog switches. The DG444 has 4 normally
closed switches and the DG445 has 4 normally open
switches. Switching times are less than 250ns for tON
and less than 70ns for tOFF. Operation is from a single
+10V to +30V supply, or bipolar ±4.5V to ±20V sup-
plies. Maxim’s improved DG444/DG445 continue to be
fabricated with a 44V silicon-gate process.

Note 1: Signals on S, D, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
