DG9431 Vishay Siliconix Low-Voltage Single SPDT Analog Switch DESCRIPTION FEATURES The DG9431 is a single-pole/double-throw monolithic CMOS Low Voltage Operation (+ 2.7 to + 5 V) analog device designed for high performance switching of Pb-free Low On-Resistance - r : 20 DS(on) Available analog signals. Combining low power, high speed Fast Switching - t : 35 ns, t : 20 ns ON OFF (t : 35 ns, t : 20 ns), low on-resistance (r : 20 ) RoHS* ON OFF DS(on) Low Leakage - I : 200-pA max COM(on) COMPLIANT and small physical size (TSOP-6), the DG9431 is ideal for Low Charge Injection - Q : 1 pC INJ portable and battery powered applications requiring high Low Power Consumption performance and efficient use of board space. TTL/CMOS Compatible ESD Protection > 2000 V (Method 3015.7) The DG9431 is built on Vishay Siliconixs low voltage BCD-15 process. Minimum ESD protection, per Method Available in TSOP-6 and SOIC-8 3015.7, is 2000 V. An epitaxial layer prevents latchup. Lead (Pb)-Free Version is RoHS Compliant Break-before -make is guaranteed for DG9431. BENEFITS Each switch conducts equally well in both directions when Reduced Power Consumption on, and blocks up to the power supply level when off. Simple Logic Interface High Accuracy As a committed partner to the community and the Reduce Board Space (TSOP-6) environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured with 100 % matte tin APPLICATIONS device terminations, the lead (Pb)-free -E3 suffix is being Battery Operated Systems used as a designator.
