DESCRIPTION
The DG9411 is a single-pole/double-throw monolithic CMOS                The DG9411 is built on Vishay Siliconix’s low voltage JI2
analog switch designed for high performance switching of                process. An epitaxial layer prevents latchup. Break-before
analog signals. Combining low power, high speed (tON: 9 ns,             -make is guaranteed for DG9411.
tOFF: 5 ns), low on-resistance (rDS(on): 7 W) and small physical
size (SC70), the DG9411 is ideal for portable and battery
powered applications requiring high performance and efficient           Each switch conducts equally well in both directions when on,
use of board space.                                                     and blocks up to the power supply level when off.

Notes:
a.   Room = 25°C, Full = as determined by the operating suffix.
b.   The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c.   Typical values are for design aid only, not guaranteed nor subject to production testing.
d.   Guarantee by design, nor subjected to production test.
e.   VIN = input voltage to perform proper function.
f.   Guaranteed by 5-V leakage testing, not production tested.
