| DG9461 Vishay Siliconix Low-Voltage Single SPDT Analog Switch DESCRIPTION The DG9461 is a single-pole/double-throw monolithic CMOS analog device designed for high performance switching of analog signals. Combining low power, high speed (tON: 35 ns, tOFF: 20 ns), low on-resistance (rDS(on): 40 ) and small physical size (TSOP-6), the DG9461 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG9461 is built on Vishay Siliconix's low voltage BCD-15 process. Minimum ESD protection, per Method 3015.7, is 2000 V. An epitaxial layer prevents latchup. Break-before-make is guaranteed for DG9461. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
