Improved, Quad, SPST Analog Switches
_______________General Description
Maxim's redesigned DG441/DG442 analog switches now f e a t u r e on-resistance matching (4 m a x ) between switches and guaranteed on-resistance flatness over the signal range (9 max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection (10pC max), low power consumption (1.65mW), 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 DG441/DG442 are quad, single-pole/single-throw (SPST) analog switches. The DG441 has four normally closed switches, and the DG442 has four normally open switches. Switching times are less than 250ns for tON and less than 70ns for tOFF. These devices operate from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim's improved DG441/DG442 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 ratings.
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.

Note 2: Typical values are for design aid only, are not guaranteed, and are not subject to production testing. The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: On-resistance match between channels and flatness is guaranteed only with bipolar-supply operation. Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the specified analog range. Note 5: Leakage parameters IS(OFF), ID(OFF), and ID(ON) are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C. Note 6: Off-Isolation Rejection Ratio = 20log (VD/VS), VD = output, VS = input to off switch. Note 7: Between any two switches.
